Just wanted to resurrect a good thread. I had pulled out my stock plugs to clean and regap (.040 to .035), prepping for the dragstrip GTG we had last year (Steele, AL). I had a CAI and C3 at the time and it seemed to run better. I am now wanting to put new plugs in after the tune so will go with the NGK step colder plugs. With nearly 45,000 miles I suppose she could use some better spark about now. The new wires will have to wait for the funds, but will be added when available.

Thanks for this thread.
