Someone educate me... Why ever change the plugs?
We all do it. But I have never removed a plug and went "Oh my god... glad I did that."
Usually you look at it, and say,..."ooo... looks good."
Years ago you changed plugs because they fouled. With electronic ignitions and nannies, that just doesnt happen... ever.
If the car runs fine, the plugs are fine...
Now, if the car is misfiring, throwing OBD codes, etc... then... might be worth it.
There is zero benefit to changing a working plug for a newer one. What? 0.5% better fuel mileage? VS a $2000 bill?
Pointless on a truck with these issues...
