Hey there folks. I'm swapping in some NGK TR-55 plugs and some red GMPP plug wires into my 3,200 mile '02 Z06. The "smog sticker" under the hood doesn't say what the plug gap is. Can somebody clue me in please?

I pulled a few of the stock plugs so far and they are all about a .055" so that is what I was going to gap these new ones at if I didn't hear otherwise...

Thanks again.

Sorry for wasting space. I was waiting on replies and scrolled down and saw the identical question... for the most part. I'll set them at .060" and be happy. I'm sure the coil per cylinder can handle that gap.

Thanks again.
