5th Gen 4Runner Spark Plug Replacement

In this video we will be replacing the spark plugs on the 5th Gen 4Runner.
This job may seem a bit involved but it is actually quite easy and will save you hundreds of dollars at the dealer. Hope you find the video useful!

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 so much, you are absolutely correct. I'm going to pin your comment if that's okay

[@arreyder1]

@@T4Rgarage Mine were a mess and unscrewed from the manifold instead of the nut coming off. Guess I'm lucky they didn't break off. Happen to know the part number on those studs? I need to grab some new ones. Thanks for giving me the courage to try this. Just one small bump to get past. :)

[@Kyle.Wynsma]

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

[@javiergardea9898]

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.

[@craiglee1707]

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!

[@T4Rgarage]

Yeah they are only torqued to 13ft/lbs so they come out pretty easy. I read that anti seize does affect the torque values by about 20% as well. Thanks so much!

[@Nextgen_Account]

Pretty simple and straightforward. Thanks man.

[@BryanSeaton]

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

[@bertharnois4088]

Easier than I expected, very good. Thanks.

[@jay_aye]

Appreciate all the videos!

[@jollytime0811]

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

[@T4Rgarage]

Thanks man!

[@joeblough4605]

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

[@NickLaFrankie]

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

[@dennisb.1996]

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

[@kyledailey1264]

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

[@derekwilliams9154]

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

[@Onetwistyboi]

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

[@Onetwistyboi]

Update: that 3rd driver side spark plug is a stubborn mofo. I ended up zip tying the two hoses out of the way and it let me get away with a 6" extension

[@teamhonzilla]

Just the video I needed Thanks! ❤️

[@T4Rgarage]

Thanks for watching!

[@mattfredericks5999]

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.

[@T4Rgarage]

I feel cheated on 🤣 Many more videos coming soon. Thanks man!

[@anatolieverhart3299]

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

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?

[@T4Rgarage]

I usually test the rig near my place on just up from the airport. Unfortunately mosaic has put up locked gates in the last 6 months. We mostly use the 4runner as a family overland rig though. We explore and camp all over the island in the spring/summer months. Doing a trip to Southern Utah in April, stoked on that. What about you? Where are you located?

[@jefferyg3504]

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

[@Chefnaee]

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

[@T4Rgarage]

The throttle body stays in position so no reset is required

[@Chefnaee]

@@T4Rgarage I went from ram to a 4Runner ! And watching this video makes me really confident in doing my spark plugs! Thankyou !

[@nadeemshahzad7980]

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

[@T4Rgarage]

I would only recommend OEM iridium plugs and only from a trusted retailer. There are plenty of counterfeit plugs out there that won’t last half as long. People get misfires like a year or two later and realize they bought fake Chinese plugs that are junk

[@toyotabrony]

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.

[@T4Rgarage]

As long as it’s the Denso sk16hr11 Iridium plugs there is no difference between auto zone and the dealer. They are both identical. Cheers!

[@NickLaFrankie]

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

[@T4Rgarage]

I don’t believe so but it wouldn’t hurt just to be extra safe

[@anthonyszeto5508]

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

[@T4Rgarage]

The engine was cold

No throttle body cleaning??

[@AeroSire]

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?

[@T4Rgarage]

Everything I’ve found states miles. Please share a link to where it states 120,000 kms

[@ismailalcheikh8925]

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

[@Michaeldpress14]

What would a dealer charge for this ?

[@T4Rgarage]

$400 usd minimum. It looks like a lot of steps but it honestly doesn’t take long and is pretty basic stuff

[@wolfeadventures]

Quote I saw was $700-800 in California.

[@T4Rgarage]

@@wolfeadventures So ridiculous!

[@nastysoda9212]

[@kobies13]

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

[@toyotabrony]

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.

You mean “Prah-cess” right? The American way. I’m Canadian, that’s how we pronounce it 🤷🏻‍♂️ “Pro-cess” might even be the correct way. How did you like the rest of the video? 😁
