I'm going to be replacing my spark plugs. Car (1988 944 Turbo S) is daily driver, no track use. Any comments on what spark plugs are the best?

The Denso Irridiums are supposed to have a hotter spark at lower voltage than platinum ones, so I'm kinda leaning towars those at this point.

Thanks in advance for your help!

Bosch wr7dc?.... Champion RN9YC, I've run them both with great luck.

 

If you search this topic you will find many threads, with some complaints that the tips of some Bosch plugs have broken off. Also I believe you will find dyno results that the NGKs were worth some hp over other brands of plug. And they are relatively cheap. See http://www.sparkplugs.com/Default.asp

 

Great, thanks! Seems as though the overwhelming favourite by a mile are the NGKs.

I also found a thread at Pelican Parts regarding the problems with platinum and the benefits of copper:

I've broken off the Bosch tips before. I just put in Champion copper. Work fine. Can anyone tell me what the differences of the NGK's are?

 

Ask Special Tool as I think he had the dyno experience.
