Hey guys,
I have stocker plugs and wires on my 02 chevy 5.3, I want to go ahead and replace em. I have edlebrock shorty headers. I was thinking of going with the thundervolts because of the super fat wires? the real toss up are the plugs i see some guys use the delco iridiums and some of you are using NGK.

Somebody sell me on what to go with?
