Plugs at 120K?

I have a 2013 Tacoma and the wife had a 2009 FJ. I change/changed plugs every 30k. They look brand new when they come out.

2022 4R Offroad replaced the FJ. Looks like Toyota says 120k for plugs. I worry that they might be seized by then. I had an Explorer that said 100k and I could not get one of the plugs to break free with moderate force when I went to change them at 100k. Left it instead of risking needing a new cylinder head.


My plan is to change the plugs every 60k. I will do it myself and consider it cheap insurance.

What are others here doing? Any problems changing them at 120K?

I don't think that it's a bad idea, won't hurt anything to change them early and as you said it is cheap insurance.
I am at 107k on my original plugs and am planning on changing them at next oil change.

 

Seeing as I do all my own maintenance, I'm with you...do it early. Much like how Toyota says to do an oil change every 10K, I do it at 5K. They say grease the zerks on the driveshaft every 15K, I do it every 10K. If they say 120K for the plugs, I'll be doing mine at 60K.

I see no reason why I'd regret doing it early and plenty of reasons why I'd regret waiting.

 

I just did mine at 126k. They definitely looked worn, but it ran fine. I live in SoCal, so no major corrosion issues. One plug was a little snung to get removed, but overall wasn't too bad. I'll probably change again a little after 210k.

 

One suggestion is to ensure the engine is cold before attempting to remove the plugs.

 

I believe it's the plugs in the dual VVT-i engine are iridium vs the single VVT-i were standard nickel.

 

My 4R is at 105k. Although not planning to change them until 120k, I will use Anti-Seize very sparingly on just the threads and not get any on the center electrode. And I'll also use 2 pairs of disposable gloves... that shit sticks to everything.
