There is no H/P gain with any spark plug--go with factory installed plugs-

100% correct info and recommendations!!!!

There are ZERO benifits with spending PREMIUM dollars for hyped plugs or wires. GM Performance Red wires and Irridium plugs make a bullit proof package! Very difficult to beat what you already have!

He didnt but,,,,,,,,,,,,,,if someone is thinking about purchasing hype plugs, I want them to be aware of the same hype on wires. Again,,,there is ZERO HP performance gain from fancy high dollar wires.

NGK Iridium plugs. They are excellent. I've used them in both my Z06s and have been pleased with their performance, longevity, etc.

I went with NGK TR-55s iridiums and GM Performance Parts Red wires

To answer bstone's earlier question, if you've ever tried to change the plugs you know that the chances of getting the wires off without damaging at least one is NIL. If you plan to change the plugs do the wires at the same time and make sure you don't damage the heatshields as you pull the wires. A wobble bar or swivel joint for the wrench is almost essential for plug #7

I'm very happy with the results so far
