Ive got a 15 with 130K. Tune up time..... Whats everyones thoughts on spark plugs. Currently Rock auto is out of ACDELCO 41114, they have NGK 4344 and couple different Denso's. I have ran NGK in my older gen 5.3 no problem....... Thoughts in this gen 5.3?
I am replacing plug wires too planning on using ACDELCO 758EE
