Hello all, I just joined this forum. I need some advice from any other 916 or 996 SPS owners. As some may know my service manual stated Champion A55V is the correct spark plug. I understand the issue with surface design plugs and there tendency to fowl under normal road use, I no longer use this bike on the track, so my question is does anyone know of the correct "J" gap plug heat range and insertion length as a replacement.
