Spark plugs? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I'm in the process of building my 2013 zl1, nothing crazy just bolt ons and a tune. I have a 2.55 upper pulley, 10% under, American Racing long tubes headers 1 7/8-3, corsa exhaust, vmax cnc ported throttle body and direct injection ID850 fuel injectors. Should I change the plugs and wires? If so what would you recommend? Thanks

plugs should be one step colder range such as NGK iridium TR7-ix or NGK Copper part #3346

Stephen12ZL1 · 04-09-2016, 07:18 PM

stock wires are fine BTW...or MSD

Okay and should I gap them or pretty much out of the box is a good gap?

Like Stephen said, TR7IX and your stock wires are fine. Out of the box gap is good, but double check. They should be .040" gap.

Okay great, thanks guys. The tr7ix part number is 3690 right?
