Spark plug change, how difficult?

those don’t look bad at all

 

Did change them today
The one closer to the cab, left and right bank, where the one darker. See the pic attached. The other four where in pretty good shape.
I started on the driver side and it took me about an hour. The passenger side it took me about 30 minutes.

 

^^^ Notice any difference after the swap?

I have some slight hesitation under throttle that feels like it could be plugs, but I only have 6,500 miles so I'm inclined to think plugs aren't the culprit.

 

No difference that I feel.

 

Tundras.com: 80k is fine for a plug swap!

Also Tundras.com: 10k is way too long for oil change intervals!

I love this place

 

Love me some Rockauto !!

 

Nobody is using antiseize on the plugs anymore? I would pop the plugs just to put that on. Well maybe.

 

Antiseize can prevent thread galling but it also lowers the torque spec by 10-20% - use with care. Modern iridium plug threads are already plated and there’s no need to use antiseize. NGK for example has a nickel chromium plate (IIRC) and are designed to be installed dry.

Any time you have dissimilar metals in contact there will be a redox reaction. In the old days of steel plug threads and cast iron heads all you needed was a little engine oil. The plating or antiseize is intended to act as a sacrificial metal barrier that separates and protects the threads of the aluminum head and steel plug (prevents galling).

That said I’ve been known to use a tiny dab of copper antiseize on spark plugs but I’m super careful not to over torque the plugs.

 

I used to really love them back in the day, but their shipping has gotten very $$ and very slow. At least last couple times I used them. So now I look elsewhere first.

 

This thread helped!! Pretty easy job (except for #6) knocked it out in an hour and a half. 58K miles reference picture

 

Run any better?
