Are you still running the stock ngk zfr plug?
Which plugs on a d16 cop?
I have a built D16 with K20 coil on plugs and a Haltech 550 EMS that we are hitting 430 but blowing spark at the top end, what kind of plugs do you guys run and at what gap?

no sir, I’m running NGK 2668 gapped at .16ith K20 coil on plug
Try running a bkr7ev(4776), that plug might be too cold, and sometimes the iridium and higher plugs don't work so well in a high boost application, gap somewhere between 24 and 18
I’ll try it, thank you for your response and time. Trying to dial this in to hit 500hp.Try running a bkr7ev(4776), that plug might be too cold, and sometimes the iridium and higher plugs don't work so well in a high boost application, gap somewhere between 24 and 18
I run the BKR7e spark plug which are the 4644 plugs. I gap them around .024" and haven't had issues at 18 psi. COP should be taking up some of the gap for blow out. I'm guessing its breaking up up top?
Yes around 7k it’s breaks up pretty badI run the BKR7e spark plug which are the 4644 plugs. I gap them around .024" and haven't had issues at 18 psi. COP should be taking up some of the gap for blow out. I'm guessing its breaking up up top?
Denzo ik27 works pretty well. I was having issues with bkr7e gapped to 0.016. It was like a fluttery misfire. I haven't even bothered to gap the denzos yet. On haltech too.
