112k spark plug change

Finally got around to changing the original spark plugs on the 2.7 at 112k miles. They were pretty toast should have done them sooner.

Truck was still running fine before I took them off. Toyota used Denso Iridium plugs from factory. Just an FYI if youve been holding off you might wanna do them sooner.

 

Interesting, they look like "double iridium tip" plugs or something too

 

The2gr-fks seems to have the plugs last longer even though it’s half the replacement interval for the v6

 

Plugs are recommended to be changed at 60k miles u did them at 112k what were u expecting ?

 

Not on the 2.7 4cyl. 125k spark plug interval

 

Interesting… I still wouldn’t let it go that long . 80k max I’m pretty ocd .

 

Just goes to show, not a big deal if you run over the sp change interval by 2x, typical of most cars these days, modern plugs work well way beyond typical change intervals.

 

Old plugs were definitely due for retirement! But then again, they could have kept going for a good bit longer if you needed them to!

 

He did them early. It’s a 4cyl. The direct injected motors have a 60k interval.

 

Hey folks, I have to help my friend do plugs on his four-cylinder. What are the best spark plugs for that four-cylinder the trucks. 2019 sr DC
