What platinum plugs are recommended for a 73 911 E? Will colder plugs help my car run any cooler?
I Installed JE 9.5 /1 pistons with Nickacil (sp?) cylinders a while ago. Temps are fine except when run on a track. Stock 2.4 with MFI otherwise. Not sure if different plugs will have any effect.
Thanks,
Chris
