Howdy Gang!
I'm new to these parts and I have a spark plug question.
I have a 2001 5.3 engine and I want to replace the plugs. I was warned away from the Bosch Platinum 4 tip plugs. I was told that domestic vehicles didn't fire hot enough for that plug.
Anyway . . . .which higher performance plugs have some of you successfully used? Which would you recommend?
Thanks
