Spark plug heat range?
I've had the car since September. Last tune-up was done by a local Porsche specialist. I just found out that I have Bosche W8DC plugs gapped at 0.036" (stock ignition coil and wires.)
The manual says that I should run WR7DC plugs at 0.028" to 0.032" gap. Are the ones I have a cooler or hotter heat range? They look a bit carboned up, so I am thinking cooler. Are these plugs a good idea, or should I change them out right away?
TIA

Thanks Russ, that's exactly what I needed! Sounds like I have the hotter 944N/A plugs. I will change them out to either NGKs or the correct Bosch plugs before I put the car back on the road.
