I'm thinking about, running an iridium Denso plug, Or OEM, any comments?

I have done some research on the Denso iridium spark plugs myself and was thinking of trying them on my Boxster until I heard two other Boxster owners took theirs out because their cars did not run well with them installed.

Thanks HBacura!!! I was scared of that. OEM it is.

I know what you mean. I would still like to find out in more detail how they ran with those plugs installed.

Porsche seems to be one of the few manufacturers where keeping the stock item or porsche upgrade is better than any aftermarket one, except exhaust . Plus with cars being so sophisticated today and the engine being so computer dependant, I'm starting to expirement less and stick to OEM.
