Geez, that's ridiculous to have to disconnect so much to get to the spark plugs.

Change spark plugs: Step one- disassemble the entire motor. Step two- change plugs Step three- hire someone to put motor back together.

Just did mine following the video. Absolutely nuts (pun intended) how you have to take the intake manifold off to access one side. The other side was almost impossible to get to as well dealing with the brackets and hoses. After making 3 different trips to the store because I kept needing different tools (my fault) to get the job done, it got it all put back together and now no more misfire engine error codes for me. Great video! Thank you for spending the time to show us how to do this.

Excellent how to video. So glad you explained thoroughly without LOUD MUSIC JAMMING! MANY THANKS! Saved $300-$400 easy!

It should be noted that '12-'18 JKs have the 3.6L Pentastar engine while the '06-'11 models used the 3.8L Chrysler engine which is going to look very different than the one shown here.

Absolutely awesome video. Crazy how long and difficult some of that was but got my coils and plugs replaced step by step.. Thank you very much for taking the time to make the video as I can only imagine what a dealer or shop would charge to do that task??!!! Thanks again for you help.

I just changed the spark plugs and intake gaskets on my jeep. Took a hour and 14 minutes. Super simple job. Thank you for making this video. It’s crazy what dealerships charge you for a job this simple and for no longer it takes.

Great video. Just changed my plugs on my new to me 2012 Wrangler Unlimited. 235000 kms and only been changed once! Managed to tackle the job in the heat of Dubai in my basement carpark! Video made it so much easier to follow. Thanks

Excellent video. I appreciate the step by step and attention to detail. I followed this and got it done. The intake torque sequence was a good addition. Really good video

Great video. First time changing spark plugs and your step by step video saved me countless hours of potential frustration. Thank you

Great video, very professional. Thanks for giving torque values for plugs and manifold

Well, thank you heaps - followed your video step by step and apart from working without something to stand on, out in the sun - no shade - in 35c temperature, all went well. One hiccup - no brakes - but running back over your video it was obvious I missed refitting a vacuum hose on the L/h side (hidden under the wiring harness). Thanks again for putting this up 👍🇦🇺

Great tutorial video especially the attention to small details.

Andy, you are the man! You are so detailed and this video was absolutely AMAZING sir! Thank you for your time.

You folks are the best! After watching the video once and referring to it while doing the work, it made for such a simple job. Just wish I remembered to order new gaskets.

Thank you for this video!!! Although it took me six hours to complete, I was able to successfully get rid of the P0301 code and tune up my Jeep! Instructions were very clear!!!

What a stress saver! This video is so detailed, amazing job!

Once again thanks from Australia for another very easy to follow video. A few weeks ago it was the radiator. Today the plugs. Wish you were closer so I could patronise your store. Have a great year!

Thanx for this video, I have a 2015 Wrangler and was going to get all my spark plugs changed . The dealer where I bought the jeep told me $330.00 to do it. I did it myself and spent $100.00 (had to buy tools too) followed this video step by step and saved $200.00 ! And at the end I got to keep the tools LOL

Thank you for your videos. Very detailed, I need that. This and the oil filter housing are my next jobs, with these videos I feel I can do them.

Great Video! Camera angles, lighting, and audio are top notch

I just replaced the spark plug and ignition coil today. The cylinder 2 misfire problem has fixed. Thanks for the instruction!

Very clear and concise instructional video thank you so much for doing these.

Thanks, that’s really going to make the job easier. Great video!

So glad I have the 3.8 its so much easier to work on than the 3.6 there showing in this video.

I really hate it when you have to remove the intake manifold to access the other side of the engine bc it adds like 30 to 60mins to the job

Thank You for posting this very Detailed and Informative Video!

That was very nice and professional done and explained very clearly and the lighting was perfect and very easy to follow, thank you

Thank you so much ! I just done mine just now ! Your video help me a lot thanks!

Great video! I even ordered parts from yall just for taking the time to make this video!

Big help ! All the details from removal to replacement

Bro that was completely awesome. So easy to follow.

Best video yet.. easy to follow

Fantastic step by step instructions. Well done, Folks. Thanks for posting.

Great video Thank You..... Crazy what you have to do to change out plugs.

Thank you for that very comprehensive video

Great video - thank you.

Helped me soo much today!

Thanks for great vide reason I keep buying parts from you guys 👍🏻

Spot on my man! Really helped a lot!

Thanks very much for the excellent tutorial!

Great video. Watched a couple times then just played and paused step by step

again Thanks heaps for the Video,, Legend. , I tried to purchase the gaskets from your website but had trouble as I live in Australia.

WOW, I can't wait ......................... Great video!

Very detailed video. Thank you!

Did this yesterday best video ever.I noticed oil dripping from throttle body when the tube was disconnected, can you please tell me what's this from.2016 jeep wrangler 70k thanks

After watching this - I’m not sure I have enough time in one day to change my plugs ! Can’t believe they would design an engine that needs partial dismantling to change “consumables”. When I trade my 2014 JK, I think I’ll be looking for a straight forward carby / distributor pre-1990 rig that you could have done a complete top-end rebuild in the time it takes to change plugs in a JK. Thanks for the video though, very comprehensive and I’ll be having this playing while I attempt the job myself (just to see how frustrated I’ll get 😜)

Changing spark plugs should not be this complicated. It's a friggin Jeep. Or it used to be.

You can actually bend those small metal brackets on the side of the intake back slightly off of the studs. I usually use a small pry bar. You just need to be careful where you are prying from so you don’t pop a hole in the plastic valve covers.

I'm looking at Japan. thanks you. The problem has been resolved.

Is it the same process for a grand cherokee? How long did the job take? Thank you for the best video on this repair! Will order spark plugs and those fancy tools!

I know we change the upper intake manifold gaskets but is there any necessity to chsnging the lowers as well? Not experiencing a leak or anything just changing spark plugs and coils and the gasket pack I ordered comes with both upper and lower

Is Dielectric grease necessary inside the coil and if so...how much should I use? I also noticed you didn't put any dielectric grease on the ceramic part of the plug which is also what I've heard to do. I'm hearing that it is and isn't necessary to use dielectric grease. I have a 2012 Jeep Wrangler JK Unlimited. What are your thoughts?

Any suggestions on other PMs or things to check / replace if you've spent the time to remove the intake?

I replaced the spark plugs on my Silverado. It was easy and I didn't have to remove anything but the plugs. I was going to do the same on my Jeep, but after seeing you remove everything just to get to them, Ill probably have my shop do that.

This is a wonderful video for the 3.6 crowd. Not sure why they said it was procedure for the 3.8? The 3.8 is hard enough in it's own right trying to route new wires and even get to the passenger side plugs but at least we don't need to remove the darned plenum.

Mine is at 62000 miles, no issue.. im planing this work ahead ..and was quoted $400 at the dealer to change all 6 spark plugs and gaskets.. because im broke, i will probably diy this. But i got a question..im not very tall and my jeep is lifted. So i can barely reach the spark plug with my hand. Even with a 2 steps stool i can not reach some of the nuts..i need to step on the bumper. I do not have a hose plier, they cost $18 each. I dont know which size to buy. Could you also list the iridium spark plugs and the gaskets parts that we need to buy? Also what do you do if you drop a bolt inside the manifold? And what year was the jeep in the video how many miles did it have ?

Thank you! I'm going to try this myself in a few weeks

What's the 1A Auto part number for the hanger magnet?

So the intake gaskets are not a sale item on your website.

Wow really great job thank you

Gaskets? Intake gaskets? Where do I get them and are they needed when doing a spark plug change?

What type and size gaskets do you need for the intake manifold? There are 6.

OMG...this looks like the spark change from hell. No it is the spark change from hell.

Do you sell the magnet as well?

Followed ur vid thanks lots of help

How do you remember to put all those pieces back? That's crazy.

it is great and nice description

Thank you very much

Best video out there

seeing this makes me glad i went with the 4.0 TJ over the JK i can change the spark plugs on a TJ in about 20 minutes. gapped and torqued

Is there a how to (spark plugs) video for a Jeep Wrangler JL 2018+ with a 2.0 engine ?

What number plug did you replace first? I'm finding conflicting info as to which side is which. I'm getting a #5 cylinder misfire and I'd love to troubleshoot it without taking my whole damn Jeep apart!

You are awesome

So the torque wrench you have pinned is 25-250 but in the video you say you need to torque it down to 7.5 ft lbs how do you get 7.5 from the 25?

So what is the best combo for plugs and packs for a 2014 jeep wrangler jk.. 116,000 miles and grandma owned. A lot of life left in the motor but needs some tlc. Let me know community..

A 2006 is a TJ And has a 4.0L, 2007-2011 has a 3.8L, 2012 to 2018 has the 3.6L. The JL is also and 18 and different as well. Also you can bend up the bracket on the passenger side rather that take the brackets off.

Yikes! 😳 that’s a hell of a lot of work just to get to the spark plugs! Dear lord!! I know I can do it! But I wasn’t expecting that much elaboration!! Great job though! And thank you for the tutorial!

Also please state to be extremely careful with fuel lines when re-installing intake manifold

I have a 2018 I changed the spark plugs on it, now I have a code u142. The vehicle will start but once I turn it off, it will not start again for a couple of hours. I can’t figure out what I did wrong, any suggestions?

is that the Intake Manifold Gasket Set or the Intake Plenum Gasket Kit

Thanks again loved it as always

Very detailed video thank you for sharing it. However, I must add that this is very poorly designed. It should not have to take this long to get to something like spark plugs.

Out of curiosity, what would happen if the threads on your plugs are longer than the old ones?

solid vid..ty

When do you change them on a 2017 JK. I have 50K

Well done overall, except for one oversight: please instruct the viewers to use anti-seize compound on the sparkplug threads! Very important.

Dang, my last Jeep was a 95 Sahara. Changing plugs was a snap. This is crazy.

When did jeeps become a pia to work on

How often are you supposed to change the coils?

Sure, its a slight pain to change spark plugs. But look at it this way, how often are you changing spark plugs? 1 hour for how many years?

Really! I miss my DOHC Korean 4 Cylinder :(.... unscrew 4 screws, change Spark 4 Plugs close it screw the 4 screws! and done!

I got an 08 wrangler unlimited and my plugs are right there, don't have to disconnect a whole lot

Thank you.

🔥🔥🔥

Thats alot of work...

So happy my 2007 JK does not have this engine. My word, how was this ever considered proper engineering. An automobile owner should not have to disassemble the intake, just to replace plugs. Thanks for the video, as we now know to stay with the 3.8L V6. I can imagine the faces of the owners of this engine, when needing new plugs, and they're quoted $1000 and being told, it's gonna take the mechanic all day to get it done. smh

Jeep dealerships currently want over $1,000 to do this job. (As of March 2024.) The first time, I was quoted around $600 back in 2018 or so, and I balked at that amount and did it myself. Then a couple years later, it was done during some warranty work; I paid only $200 for parts and labor because I knew enough to tell them the hard work of getting to the plugs would be included in the warranty work. So, they discounted it and I was fine with paying that; I know they need to make money. But this time, I'm having the valve cover gaskets replaced under the lifetime power train warranty and they initially asked for over a grand for plugs, then discounted it to $600 for overlap of work when I called them out on it. Total BS. BTW, they wanted $1800 for that but thankfully I have that warranty. So they're doing that and I'll be doing my plugs myself again. You'd think, just to earn some goodwill with a new customer, they'd take a couple hundred bucks to screw in six plugs and I'd be happy paying that. But $600? No. Thanks again for a crystal clear instructional video! he first time, I was quoted around $600 back in 2018 or so, and I balked at that amount and did it myself.

Wish I seen this before I bought a wrangler. Everything else is easy to work on except changing the spark plugs 😂
