I had them on my 2014 Z51 car with long tubes and knn cai. After a lil while, I chunked them and went back with NGK. I lost a couple mph in the 1/4 mile. Depending on your build, you might of not had a cold enough plug. What was it gapped at?

Yikes! Among other options, either you had some serious timing issue or the plugs are way toooooo hot! DON'T do again what you did here!

Think they were gapped too big at .30. I got them down to .25 holley and hp tuner logs showing misfires gone. I have one step colder I may go two steps once I get a bit more logging done and sent to my tuner Chris Crawford. Will report back.
