NGK TR55s and MSD 10mm wires, swapped out at 50k miles.

Can't say I've noticed any difference....just a maintenance thang.

I was talking to a guy at a speed shop about this. He said do you think GM would spend the $10 a plug that it costs for iridium plugs if there wasn't a benefit over the $3 copper plugs. The extra cost to GM for those plugs for just the 2005 GTO is $672,000. For the C6 it is $2,128,000 for plugs for just the 2005 model year. He did add that if you radically changed the engine, heads, cam etc... there would probably be a better plug. If you use nitrous there definately is better plugs.

I did notice a difference on the @ss dyno. quicker lift of front. better throttle response. I put the TR55's and Taylor 10mm's
