Solid videos, no fluff, just what you need to know. A few humble comments... - there are four clips on the air filter cover, not three, but if you own a 4R and do your own maintenance, then you probably know that. - Be very cautious with the two lower nuts on the air injection tube. They are prone to rust, especially on the driver's side. And once they are rusted it won't take much to snap the stud off. So if they do come off, some high temp anti-seize should be wiped onto the stud during reassembly. If they won't come off then you can try penetrating oil, and pray, but they will likely snap. FWIW I wouldn't recommend heat as you have a whole bunch of hoses nearby. So if you do snap the stud, then you can get in there with a Dremel and cut/grind the stud flush and them drill out the stud and replace it with a bolt and nut. It's cramped and you'll need to order a drill chuck with a hex on the other end. So you can extend the drill to get down in there. Becareful, take your time and you will save yourself $1k for the dealer repair (they will want to replace the whole exhaust manifold).

Thanks man. Just finished job this morning. For anyone reading this, you can get OEM plugs from Frontier Toyota in California for $11. There was a shipping cost but even with it, it was still cheaper than any aftermarket plug, at least where I live, and they were shipped straight to my door. I do recommend to remove the air tube gaskets before removing secondary air injection pump. I knocked over gasket and lost it in my engine. Fortunately found it after about 20 minutes

One of the best videos I’ve seen on vehicle maintenance. Straight to the point and easy to follow walk through. I looked under the hood earlier and once I spotted the spark plugs I said heck no!! lol. Thanks for all the info, you made it look easy.

Doing mine right now while watching. Thanks! Saved me almost $300

I was shocked at how easy those plugs came out. Turns out, anti-seize on plugs isn't a thing anymore. It actually causes an over torque situation. That information alone gives me confidence in changing the plugs diy. Great video!

The combination of your lighting, angles, and explanations gives me confidence to do these jobs. A few times I've brought up your videos for reference when I was under my 4Runner...lol

Pretty simple and straightforward. Thanks man.

Easier than I expected, very good. Thanks.

Appreciate all the videos!

I use your videos to do my own maintenance. Thanks!

Great videos, I'm going to try all sorts of stuff I had always been afraid of doing on my car. Thank you.

Just the video I needed Thanks! ❤️

Great video. I will use it tgis week when i change my plugs. Thanks!

Hardest part was honestly those plastic sensor clips. Great video! Super easy for the amount of stuff to disconnect/move around

Ty for this. Just hit 110k on my 2017, gonna change them out this afternoon

Awesome video! Thank you brother! You hooked me up.

Great video as always!👌🏻

Great tutorial. Only took me about 02:17:00 to changes the plugs. Love the channel and will be subscribing for sure.

Thanks for saving me from the stealership. You the real mvp!!

Excellent video. I had to use my other two favorite 4runner mechanics (car care nut and Viking) to help with this change. Take your time, use a torque wrench, and enjoy the ride. I'm glad to see another video from you and hope for many more. PS you're still my favorite YT 4Runner mechanic 😂 I also changed my PCV valve (Toyota 12204-31110 PCV Valve) which is behind the furthest spark plug in the driver side. A real knuckle buster but a good time to do. Thanks again.

Another solid video! I'm still trying to come up with new video ideas since you've knocked out most regular maintenance. Here's what I got: 1) Install GMRS/HAM antenna 2) Customize image that appears on start up screen 3) Install air compressor under hood 4) Re-torque driveshaft bolts

Thank you 🙏

Pro tip do not take the lower exhaust nuts out. They will most likely be rusty and snap. You only need to take the top ones off.

Yeah, I'll be using this vid in the near future to do mine. currently at 90k Km's. I understand you're on the island! where about do you normally take your 4runner offroad?

Love the video! Question, do you have to reset your throttle bottle after unplugging the air intake ?

Can I use the later 5th Gen spark plugs in my 2012? Or are there reasons to stick with the cooler spark plugs

I bought the DENSO iridium spark plug oem replacement at autozone. I had to look them up first to see which type of spark plugs and of course. DENSO. So they are a bit expensive but u get what u paid for. For oem, it’s worth it. I change them 20,000 miles early before 100,000 for my 2015 lifted Scion xB. Yes that’s very very early but I also want to do that as ahead of the schedule. @T4Rgarage I know buying from Toyota dealer is a better choice. But buying at autozone is also fine? Again, always buy an oem replacements. Never an aftermarket spark plugs.

Hi would you Recommend the NGK ruthenium spark plugs in 4runner instead of laser iridium

Any need to disconnect the negative terminal on the battery during this?

Did you remove the plugs with a warm or cold engine? There has been much debate on the webs.

Anyone ever used NGK 4469? I installed them already but willing to take them out and put OEM if they are not good enough. I did not do my own research before buying them and don’t want to live with guilt

Not to split hairs, but doesn't the service manual and Denso's tech specs say that the service interval is 120,000 kilometers, not miles? Therefore 75,565 miles?

No throttle body cleaning??

What would a dealer charge for this ?

ez pz

Toyota owns denso so they didnt rebrand them they just marked them up to stealership prices lol

Jesus Christ $400-$600 bucks. Just to change the spark plugs. What a major rip-off. Just buy from the dealer or autozone and DIY.

process or pro cess which 1

process not pro cess where did u go to school son that sheet is irritating
