sk20r11 Denso in my V8.
Fairly good deal on them at AutoZone right now. Enter code AG26 and get 20% off. Pick up in store or shipped.
I'm getting mine on the way home to be put in this weekend.
Almost went with the IK20 (supposedly the performance Iridiums) but they're supposedly only rated for 30k miles as opposed to the 100k miles on the sk20r11 plugs.
50¢ difference between them. sk20's were that much more.

Which one would you recommend for someone who is now replacing the plugs at 137k miles?

If you don't want to have to worry about them for the next 100,000 miles go for the sk20r11.
Thanks!

I actually ran the stock ratio of 50/50 denso/ngk on my last plug change only because the local store had both and they were w/in about 5 cents of each other. Having done one plug change and about 8k from the next I have to say it is not something I dread. Specifically, I do not mind changing plugs every 30k on the V6, especially since its relatively easy, minus the rear left plug. Running iridium plugs seems like a swell idea to extend the service interval but honestly, 30k for me is plenty to replace $18 worth of standard plugs. Also, given recent accounts of head gasket failure, at a minimum, 30k is a fair diagnosis of both oil and visual inspection of plugs to determine which cylinder is or is not on receiving the proper fuel / coolant mix.

All good, true and valid points above.
Got mine changed out today at 107,500k mies. Had 8 NGK IFR6A-11s in there. I don't think the PO ever had them swapped so I believe they were the factory plugs. They looked fine. Was a bit surprised to find 8 NGKs in there. Maybe only the V6 had half NGK half Denso?
I thought the Denso were stock that's why I went with the Denso SKR2011, guess not. They were recommended in the manual though. I've used NGK on cars in the past and have never had an issue. No big deal. I'm sure bth are fine plugs. Happy with my choice so far.
FYI- the original plugs are no longer available and have been replaced with NGK IFR6T-11. No clue what the difference may be.
The spark plug job wasn't bad. Just be careful pulling the plug clips (I used a plastic spudger tool to help pull the plastic tab up on the clip. I either lost one of the round rubber O-Ring grommets that go between the coil pack and the cylinder head, or it was missing from the factory. Don't lose one! The only way to buy one from Toyota is as part of the entire coil pack assembly - $115! Thankfully I found a local junkyard with one and pulled it off a highlander coil pack (exact same O-Ring). They just let me have it, but what a pain.
And be gentle tightening up the plugs. When I was 20 I over tightened a spark plug, stripped the hole and had to re-tap it. That doesn't always work so I was lucky. I torqued mine to about 16 lb ft. That's always my big fear when doing plugs. Breaking something else.
It's always a pain getting the spark plug socket off the new plug once it's tightened so some folks just use a deep socket. Your choice.
Have different length socket extenders if doing a V8. Master cylinder, air box and various vacuum hoses can be easily overcome obstacles.
I changed the oil while I was at it. Had to buy yet another end cap oil filter 'socket' tool.
I was going to clean the throttle body but don't like doing too many things to an engine at once. If something goes awry afterwards it's helpful to know which job caused the change. Will probably clean the TB in a month or so when I change the diff and transfer case fluids.
Have fun, be patient and good luck!

If u go to the dealer they will sell you 6 Denzo plugs. Oem means go to the dealer and buy. This will set u back about 19 bucks.
I replaced mine with 6 Denzo plugs from Toyota just as the manual reads. This gives me peace of mind that the engine is firing as it was designed to fire with the plug that Toyota specifies. I'm not a mechanic by any means but some things like spark plugs makes sense to buy oem. Tacomaworld.com has some great DIY and info on this if u want to research in depth.

Calm down bro!!! Nobody is stupid here just fun and games!!! I paid a little over $3 each for the plugs! I also got my tranny oil for my 1st gen taco that same visit for less than autozone. Just tell them to lower the price!
I buy my oil filters from the dealer too! They are designed for our engines with the proper drain back valve and more filter material. They charge me $4.00 for a synthetic filter.
More good reading.

It's obvious you aren't a mechanic...Buying Denso plugs from Autozone....you're buying the EXACT SAME PLUG the dealer sells. There is ZERO difference. Denso doesn't sell a special plug to Toyota dealers only. Do you buy Toyota oil too. And guess what....Toyota doesn't make oil filters either...They are made for them by companies like Denso and even Fram. Maybe you should do a little research...the internet and library is full of information. It would save you a lot of money instead of listening to the Dealer propaganda. Show me that buying Toyota only parts is BETTER!! I've kept a total of 4 vehicles well past 300k miles on NON-OEM plugs and filters (and pretty much most parts)....two of them went well past 400k miles. How many vehicles have you kept for that many miles???

Not by a long shot.
OEM NGK or Denso @ partznet.com is $2.98
2006 TOYOTA 4RUNNER Parts - Conicelli Parts Center
Standart NGK for same 2006 V6 engine @ Autozone is $5.49

Careful guys the Mike in NH loves to argue and blast negativity to give sites like this a bad rap. He or IT can't be nice or positive when saying something so I say its better that M says nothing at all.
Don't fall for it, M is just looking for a fight.
And all the opinions offered on this thread should be well taken.
Elvis has left the building- Good night!!!

Oh yea ive seen his rants on the site. Yea like I said I'm not spending anymore cash on spark plugs and oil filters! I've done the research and I've learned (from my dad ase mechanic for 35 years) and techs on tw that if u follow the service manuals cars go forever! For that reason aI have a Subaru gl with well over 400k, never rebuilt!
Our trucks are built with super tight tolerances and for me I get a little piece of mind when i replace very specific parts like spark plugs as recomended in the manual. Get on tw and read, I have and I'm just sharing what I found. Enjoy
