What Spark Plugs are you running?

Is the factory plug the one to go for or is there a better one on the market?

Cheers,
Stu

Better is relevant. Factory works fine unless you have pimped out the engine.

I'm using NGK 94279 FR6AHX-S Ruthenium HX plugs. So far they have been great plugs.

Beru fitted last time I changed mine. Cheap and correct so you can't go wrong.

I've used NGK, Beru, Porsche, and Bosch. All have worked fine and I couldn't tell any difference between them.

I buy the cheapest Iridium name brand plugs I see. They last longer.

Called a Pelican "Porsche Specialist" for guidance on the ~10 choices of plugs listed for my 3.2L engine. She asked if I tracked my car which would affect the proper plug choice. Neither of us could determine exactly how the internal combustion process would change with track vs. street asphalt conditions. She thought the gap might be different - etc...
It would seem the TStat, H2O pump, fans, ECU would all operate the same. Commentary from those with facts???
