Spark
 

Anyone know off hand what the Porsche recommended spark plug is (oem). for some cars it is very important to use a very specific type of plug or the engine will misfire. just wondering for future reference.

Hi Sphinx,

I would normally say just get the cheapest single tip copper plug. The DME is set for the copper tip and injector duration. Maybe go with a single tip platinum.

I say normally because I recall your work on the 1986 944:

Please update your signature line above under "UserCP" with car info and such. THX

Multiple tip plugs may not give you the detonation timing needed for full effectiveness.
