If the pulstars ignite the fuel faster, then the required optimum timing will change, so to really know for sure how much extra (or less) power and torque you can get, you'd really have to tune timing for the best results with the standard plugs, and then retune the timing for the pulstar plugs, and then compare the power and torque figures for both runs. If the pulstar makes the fuel burn faster, and if the engine is already tuned optimally for the standard plug, then the timing which was optimal for the standard plugs, will likely be a bit too advanced for the pulstar plugs. So the pulstar plugs would in most cases require a timing map that was more retarted than the standard ignition timing map used for normal plugs. If this was done, you may get closer to the results pulstar claimed were possible to achieve.

I was very skeptical about Pulstar Plugs. After installation, my Jeep can now do wheelies, the rip in my seat in now gone, and ice cream tastes sweeter. Thanks, Pulstar!

I dyno tested these plugs on an old tired 2001 saturn SL2. regular plugs 100hp at the wheels. Pulstar plugs 105. I was impressed with them. We made 3 pulls with each plug combo and took the average.

You're the real MVP bud. Thanks for the vid.

I have took the plugs out of my car and now it makes the engine turn faster on the starter motor, it's gunna be fecking quick when I get it running. ....

Awesome! Thank you for taking the time to record and post this proof of theory...

Interesting, thanks for running the tests.

Good job testing the plugs and thanks for making the video.

Nice video , I'm running a 1972 Pontiac 455 H.O. , bored .60 , roller cam , old school TRW L2394 pistons with a torker 1 intake and a Holley 850 hp series carb , msd ignition . Just researching spark plugs and advancements and enjoyed your video , no nonsense information , thanks for going to the trouble of doing a real world test , helps a bunch.

I played with Pulstar Spark Plugs awhile back. I'm a risk taker and like to try stuff out. Had them in my 2001 Acura Integra. Feels pretty good for the first 9 months after driving maybe like 9,000 miles with them in. My engine car start shaking violent at random and drive smooth again. After a bit more driving, it was undriveable. Took it to the shop, the mechanic gave me lecture saying the plugs are too strong and the engine is not design to handle it. It cause the pistons to be misaligned. After all said and done, the mechanic replaced my spark plugs with brand new good ol NGK spark plugs and aligned my pistons for $140. There are a lot of negative reviews for the Pulstar plugs. It's really not worth it. The reason I decided to try them was because of the benefits and hoping the problems people had were just special cases. I think the chance of failing is like a 50% chance. Good luck if anyone still wants to try it.

I have my plustar still in my car for 9 month and over the limit on mileage. still starts up and performs great.

$200 for power that doesn’t really make a difference? LOL! Thank you for testing! Much appreciate the effort and expense spared to do it.

Keeping them honest!!! Good job!

Thanks for giving us the straight scoop on this! As they say buyer beware.

That just answered all my questions thanks guys

thanks for the contribution.

I wouldn't pay 25 bucks for a spark plug anyway....

Tq for a fair and square review... I agree on your reviews with regards to those pulstar plugs that there are more other efficient ways to increase hp and torque.....

Thank you so much for doing this test man! They seem to only start to shine at 5000 plus rpms. Not practical for a daily driver. Cheers!

I had six of the iridium Pulstars in a 2002 Chevy Trailblazer LTZ for quite a while. I don't know how many miles, but it was for several years. I'd venture to guess that they well exceeded the 50,000 mile claim. I finally had one fail on me on a drive from Kansas to Georgia, in Tennessee. I was driving her really hard and it was during the summer. I started to get a misfire. When I examined the plug on cylinder one, where the misfire was, the entire enter electrode was worn or broken off. It just wasn't there. That was, apparently, causing the misfire. To make a long story short, I replaced all six of the spark plugs with the comparable OEM iridiums. I can definitely tell a difference. The Pulstars had more noticeable power. It certainly isn't the difference felt like a supercharger would be, or a cold air intake with exhaust. It did make a noticeable difference in the Trailblazer and her 4.2 Vortec, however. I miss them. As for the other five, there was indication of their being worn. There's no question about that. It was like the iridium tip point had kind of melted a bit and slid to one side of the electrode. They're still intact, though, and they had been in the Trailblazer for well over the 50,000 mile claim. I'm considering getting another replacement and running them with the other five for a while, and also getting some for a 5.3.

thanks for the review, i was looking to buy these.

I put a set in my 2002 aprilia caponord motorcycle and so far I'm very pleased -

Put one in my lawnmower. Went from 5 hp to 16 hp. Had to go from a 24 inch blade to a 40 inch blade just to slow it down.........

They are made is USA! People complain about the cost. They aren’t going to make me broke. These are very good quality plugs and the only brand I have in my vehicles. I stand for the flag! Thanks Pulstar

The 11hp claim is below the standard deviation of any Dyno. Meaning the difference, if any is beyond measurement. You made the correct conclusion

Thanks. I was considering them for my Audi S5 but will now go for the Bosch platinum @ £20 per plug. All the best..............

Thank you for confirming the doubts. When I bought them. I noticed drop in early torque too. As well as they died on me suddenly within 10,000km. Engine started misfiring. I went with the classic choice NGK. Safe call. Engine is back to stock performance now.

Thanks for doing this test and making this video! I've been wondering about these plugs since I heard about them a couple of years ago. $25 per plug is outrageous! At that price they'd need to deliver far more than what your dyne showed. Hell, they'd need to deliver far more than what the manufacturer says they will at that price! I'm not a buyer. Thanks again!

Excellent test

Did everyone not hear it breaking up in revs?

Fixed my VTX from fouling all the time. Luv them!

Thanks for doing the test... =]

I am grateful to people who do real Dyno pulls on a engine and do the best possible Dyno runs for accurate runs.I know it's not a definitive answer across all engines but claims from MANUFACTURES NEED REAL WORLD DYNO RUNS ON ALL ENGINES BY A INDEPENDENT TESTER NOT THE MANUFACTURE WITH THE GOOD THE BAD AND THE UGLY!!!!!THANKS FOR THE VIDEO!

LS1 cars came with bad plugs(long lasting though) from the factory. so any change would show improvements

All I heard is that Lion of an engine strapped to a stand, my hats off to the builder of the beast.

BUUUUUUUULLLL SHIIIIIIIIIIIIIIIIIIIIIIIIITTTTTTTTTTTTTTTTTTTTTT

By the diagram they just have a spark gap, that will drive the coil to peak power which will improve performance a bit, same thing with those "power improver" things you put on the coil wire. For the price investing in an MSD unit is probably better in the long run.

Yeah....the smoothness/power/torque difference I've enjoyed for over 25 years with this technology, first with DirectHits, and now these plugs, is something obviously too few have taken advantage of. If nothing else, the low rpm smoothness and characteristics is consistently appreciated....no other way to achieve that firing consistency result. Its a no-brainer everyone.

You mean the stock 3.48" stroke. Ford uses a 3.5" stroke, stock in the 352FE, 352W, 351C and 352M engines. Heavy used the 3.48" stroke in their 350 and 305. The funny thing is back in the mid 60's Vic Edelbrock took a 350 hp 327 , broke the engine in according to GM specs and put it in the dyno. It only made 313hp. He tried a few thing and when he swapped plugs from AC to Autolite the motor picked up 5hp. This guy is going from Autolites to these new plugs. So if Vic had had them back in the day he could have picked up 8hp must by changing spark plugs! Hmm.. I wonder what would have happened if Firestorm plugs had been available! They induced a plasma into the combustion chamber instead of a spark, providing a cleaner, more thorough burn of the airfuel mixture. They were way more efficient that any sparkplug ever made, but the inventor was met with resistance everywhere he went. Thesparkplug companies didn't want them because they lasted too long. The oil companies put up a fight because they improved mileage significantly, and the Auto Manufacturers didn't want them because they owned spark plug companies and were influenced by the oil companies. Every time someone comes up with a better mousetrap, somebody else shuts them down! Shit!

Im only utilizing one pulsestar in a 2 stroke bicycle engine, but im at twice the gap the motors supposed to have. I gained noticable power, and was able to get another 800-1000 rpm before it started 4 stroking. Ive noticed in other videos, that the gains from running pulsestars comes more when you increase spark gap than running the original gap.

Great vid,,,, truth not advertising.

I have them in me 2002 Holden and I can say I didn't noticed any difference but I did notice how smoother the engine idles. I actually bought them for the slightly better fuel economy and see none of that either but maybe a few extra ks per tank but who would notice that.

great vid.. thanks..

The reason they cost so much is because the electrode is made from powered unicorn horn .

reminds me of splitfire plugs in the 90's claiming all good things and got sued for false advertisement which eventually went bust

Thank you

For a bit more you can put a 100 HP nitrous shot on it , and FEEL the power gain, and stick with the $2 AC plugs, clean and gap them every 15k miles, I hate paying for the E3 plugs, and indexing the plugs can help, ( placing the ground electrode in the same direction in every cylinder) it will effect where the flame starts, and can lessen possible fouling, from incoming fuel, in some cases, but basically the only time you will see a real gain, is if there is something not working properly, and a new plug fixes the problem. Just like hot coils, it's not going to make power unless the original coil wasn't capable of supplying enough current to do the job, higher compression can require more voltage and amperage to start the fire! Still a great video,

At $25 per plug, they are "snake oil" and a rip off too as far as I am concerned. I'll stick with my Autolite plugs and save a bunch of money.

nice sir

The problem is: you did not factor in the shorter pre-ignition stage. The reason the plugs did not perform as well is because the timing needs to be retarded by 2 degrees or more. This is because the spark is so much more powerful, the start of the fuel burn flame is much bigger making the actual explosion of the fuel faster. To take advantage of this you should have redon the timing set up to work with these plugs. but instead you set up the timing to work with normal plugs. A computer that is able to adjust timing according to how these plugs work can take full advantage. Computers that cannot will not as to the reason there is such a variance in results. Do the test again and this time adjust the timing for how these plugs work and you'l see. Also they are now on the 4 or 5th generation plugs as they tweak them for better performance and reliability. How many changes has autolite gone through? Not many.

i have used pulstar 2x's $13 per plug on a 2005 Cobalt ls 2.2l 4cyl and a 2008 Cobalt SS/TC tuned 2.0l 4cyl . the 05 gained 2 mpg the highest i was able to get off the regular plugs was 29.99 after the pulstars it was 31.99 and when getting on it for a whole 2 weeks driving around town i lost mpg from the lowest i had ever hit....! the 08 SS/TC i drove around for almost a week using my stock tune without any problems but when i engaged my tune and did about three pulls the plugs misfired in the middle of the third and stopped producing power was able to drive regularly all the way home but every time i tried to get on it at all it misfired . the plugs do seem to work well with naturally aspirated cars but not beyond that

You ain't going to feel the difference of any spark plug, unless the ones it replaced isn't firing! i run either NGK, regular AC delco, or E3, not saying there can be gains, it's not going to be night and day differences, without changing something else, fuel, boost, nitrous,

why not test out 10 different sets basic , cheapy $2 plugs . autolite , bosch chanpion , ngk denso etcc . You might find basic plugs can out perform the high dollar pulstars . Wouldn't that be embarrassing . .

wow unless ur looking for 4 more HP plus star must hate u. thanks for running actual test I heard that silver spark plugs have the most heat conductivity and copper coming in second than iridium down low and platinum last

Now, unless they drop the price on those pulse suckers I might as well just jam in a supercharger O_o

How to steam clean the engine constantly while you drive. Get A piece of paper and twist it clockwise until it looks A twisted blunt. Get in as much twists as possible. Then put it into the air intake before the air filter. Make sure that it is parallel with the intake tube and secure from being sucked into the tube. Drive the car like normal for about half an hour and then pull over to A parking lot and get out. Go to the back of the car and put your hand in the exhaust stream. You should feel damp vapor coming out of your exhaust. That is how you know it is working. This should give you A few MPGs better mileage for A few reasons. Coolant is A lubricant, the coolant is already hot and turns to steam easier than if you have A mist system. When water turns into steam it expands A lot. You should use environmentally friendly coolant if you use this trick. To protect your health and others. I have not done this on A rotary car yet! So you are on your own if you do this. Try it or not, as it may damage your engine. The coolant will have to be checked more often as well.

Have you tested the Brisk EVO plugs?

As long as people continue to spend hard earned money believing good marketing lies...you'll see BS claims like this. Anyone who's been around awhile will remember Splitfire plugs making the same promises, with the cost being around 4 times as much as any other spark plug of its time. The ONLY way a spark plug can make any more HP is by burning more fuel.

stock stroke is 3.48, and did anyone notice the water drip from the head bolt after the second pull?

Is 42deg normal for those engines? Seems like a lot for a highter compression engine

I tried these in my lawnmower the other day. I can't believe someone would need such a large power gain on a 8cyl. I was having a hard time holding onto Bessy my old and true 20" brigs and straton powered rust bucket. Wow In a V08 that must be like having a rocket engine attached to the back. Look out race tracks we have a game changer.

Could u test I.M.C.A. 360 crate engine please or how close is your late model to it???

I would like to see an A/B test on a variable ignition timing engine.

thanks

That gain could have just been from the engine breaking in a bit more. I wonder if you put the regular plugs right back in and ran with them again if the power would have stayed where it was with the Pulstars?

I see there is a good small increase in an engine like the one shown as in the video, but at the same time how would it do in a smaller engine is the question. I have seen my friends use this in their vehicles and they have small engines and they get about 7-10 more HP from it

Wonder if these plugs work better on a high revving motor.

You guys need to try on coil pack ignition

Troll... on the internet... Oh yeah I have heard of such things.. But I usually need a boat for that.. but then I am old and don't know any better... Oh I love it! gear heads.. we are all the same generation after generation.. we are gonna test a spark plug but before we do we just have to tell you all about the mill we are runnin'.. I just LOVE IT!.... whoa 42*.. woof! I agree with your finding..But like I said I am old and never really know where I am... carry on boys.. love the channel!

For 200 small ones you can get 8 spark plugs at a junkyard with a whole engine included

Try the E-3 spark plugs

What about fuel economy? Are the Pulsars worth it for fuel efficiency for added range?

Can wait for the English version.

what if you need a special ignition coil for them or plug wires

Did they index the plugs?

It looks like they have a spark gap inside the plug, this will 'force' the coil voltage to increase which could add some power. The same could be done by widening the spark gap, which will actually provide more improvement in combustion, up to the point where the spark can no longer jump the gap.

I bought a set for my 1998 Honda Accord 4 cyl coupe and achieved 31 mpg at 80 mph on a 1200 mile trip from Detroit to Dallas. The car is rated at 28 mpg; that's an increase of just over 10%. They didn't work very well in my 2008 VW Jetta Wolfsburg with the 2.0 turbo though. That engine ate the side electrode on all four plugs by about 25k miles! Weird!

In my experience, it takes a little driving for the ECM to adjust to the Pulstars. Using a chassis dyno for torque and horsepower plus very precise fuel measurements will tell a more accurate story, with a few days of driving on the Pulstars before the test. The manufacturer has done MANY of these.

im guessing those plugs burn hotter but dont that mean u need more air and fuel input for them to be anygood i can see on a electronic controled engine to work it may tune it self a bit for the plugs but this one has a carb i would re tun the carb and do this test again just to make shure

I would assume a small bump in timing for the standard plug would have given the same results

My investigations show the plugs increase the HP, the problem is, the plugs are not reliable. The electrodes melt or erode prematurely and the porcelain cracks in a short period of time. In top the spark is so intense that pierces the top of the pistons.

Multiple spark ignition system is about the same price, and does the same thing...no secrets here..

yep but how far will they go, how reliable are they

So basically, the improvement in Hp/Tq occurs when the speed of wavefront becomes a limiting factor (4k RPM+). So, unless you're racing, there's no benefit to using Pulstar in regular street/beater cars.

A spark is a spark. Once the fuel is ignited it burns no matter what the plug is doing. Machines cannot benefit from a placebo effect, But the owners can. I would say that a single run would be inconclusive.

I installed it in my Harley and the difference was huge. Excellent product.

Jesus that revs

Ya Split Fire made the same claims 30 years ago. Can you still buy Split Fires?

"Honda civic Habread"

You have to reduce the timing by 2 degrees to get your horsepower. Pulstar reduces the need of so much timing because the pre-ignition to explosion of the fuel timing is reduced. Making more of the fuel being burned done so in the explosion of the fuel not in the pre ignition nurn part. You also used a carburetor engine. Computer controlled more adjusts to the differences which a rear wheel dyno will show instead of the set up you used. These are also 100,000 mile plugs.

2:43 and 3:28 sells it for me...you can hear the engines running loud as fuck with the first set and sounds like its purring with the Pulstars. Maybe on this Dyno they can really only see the slight hp increase...says nothing about fuel economy, emissions, all the other potential benefits

I have one question with this test. Are the MSD box and booster hooked up? If they are installed, this comparison test is a waste of time unless you are trying to determine what spark plugs would be best for your hot rod that has an msd box and booster installed. For the daily drivers, this video doesn't help.

I agree. It's funny how spark plug manufacturers, like this one...keep making claims...just to sucker a few people into buying them. Two hundred bucks could go to much better ways to increase HP.

A carbureted engine, as this appears to be, may not be the best application for these plugs. Possibly power is available, on the upper end would be nice, if Lamba O² readings allow for a little more fuel. A close comparison of all the data may reveal something worth thinking about. You're in for $200 already... Best of luck.

If I am not mistaken these plugs will not work with a msd or any copies of them. CDIs need a certain type of plugs to work properly like resister plugs. All most all of the spark plugs today are compatible also you have to run certain wires to. I have tried to run the nology capacitor wires with msds too and got misfires. Nology wire work fine on regular ignitions just not CDIs. It might be a fair test if you did it with a hei distributor or points. It's better to have the capacitors in the wires than the plugs anyways. Just read the instructions for the ignition box and you might find out the plugs aren't compatible.

That's one pissed off engine. "Merica fuk ya"

Thanks so much. Not worth it at all especially with a car that takes around 4-5 hrs to change plugs because the motor is trans mounted. I have a 2008 Highlander with 170k miles with the same plugs. I’m replacing with OEM plugs for sure.

Why not just buy an ignition box then? Like the MSD or some other cheaper one. The MSD sparks multiple times. A guy could probably find an ignition box like the MSD street fire ignition box for about $175. I'd like to see Pulstar v.s. ignition box. I would be about the same price too. $30+$175 for the MSD + standard plugs or $200 for the Pulstar Pulse Plugs. Those MSD systems last a long time and are trouble free as long as you hook them up with quality connections and mount it where it's not out in a damp location. I put one in my brother's 79 Dodge van 10 years ago and he's never had any trouble with it. He said that it gets a little better mileage after I installed it. I got one at a garage sale for free. The guy said it didn't work. It works fine it's on my truck right now. I wouldn't want to get shocked by it.

Looks like pulstar plugs have a capacitor in it

Engines are built with specific plugs in mind. A hotter spark on an engine not designed for it would mean eventual ruin.
