Hey guys,

I'm wondering if my sparks plugs are in need of replaces for tune up. I don't know when it was the last time it was replaced. I don't want to do something that can potentially lead to future problems which seems to be the case for these trucks and how long it takes to do replace all of them (4-6 hrs). There is no timing miss. It only seems to provide lower than normal MPG of 11-13 mpg.

Here is pics of one of the easy to get to plug.

Thanks guys.

 

Fromthe looks of them, I would change them out. Just changed mine a few weeks ago. MPG is way better now. They looked identical to those
