Installed Splitfire Plugs, Lost Midrange.

[Psymon]

I replaced the NGK platinums in my R32 GTSt with some of the splitfire plugs yesterday. I took it out for a run and it seems to have lost power around the midrange. I set the gap to 1mm on the splitfires. Is this too wide??

what was the gap you were running previously on the platniums? eitherway, try .8mm on the spitfires and see if that helps your problem.

I set the gap on the splitfires the same as what was on the platinums.
