What type of sparkplugs are you guys running in your modified 951s? What type of gap are you using? Does anyone know the best spark plug to run for power/anti-knock? Anyone using iridium sparkplugs? Any feedback would be greatly appreciated

Thanks,
Sean

The tuners in Germany usually go to WR 6DC instead of WR 7 DC.

I use NGK copper BPR7ES. One temp range colder than stock. Very good self-cleaning plug, super cheap, and highly recommended to me by a Porsche service manager with 20 years of racing experience (and he doesn't even sell NGK's, so he wasn't gaining by making the recommendation).

NGK R's. BPRS7ES. Stock gap around town and under 16psi. I've recently learned to reduce the gap (0.022-0.026) when running high boost (at the track).
