97 camaro m6 ported H/I 226/234 ai cam kooks headers efi 24x 467tq 455hp. im running into a problem with spark plugs. I've ran tr6 and champion #13 the car didnt seem to like those plugs. im gonna try tr55 at .040 any suggestions as to what plug/gap would help.

What heads you running? Lloyd recommended me Autolite 104's for his LE2 heads, and that's what I run. He also recommended a .035" gap on them. I was fouling NGK's bad but the Autolites work awesome.

stock ported heads. i think im gonna go back to tr6 and try .035 i think last time i ran the plug at .04

Why the cold plug? Whats your static compression?

What exactly was the problem with the plugs.... fouled, eroded, just didn't run right, etc?

Surprised the NGKs were fouling, I thought those were good for our cars?

i agree, seems like too cold of plug for an n/a setup. i ran though when i ran nitrous and car ran like poop till it was up to temp.
