Your truck runs for 100,000 miles with the same plugs. I put in new plugs about 15-20 tanks of gas. I save old plugs too!

Dont mess with them until they are fouled like Dipshit said. If your motor starts breaking up or feeling sluggish, then check the plugs first. Its kinda a matter of know how your motor runs.

Only if you actually ride phelps
