The W7CC and NGK 6-series mentioned are both decent plugs. Stay away from the Bosch Platinums (regular, +2, +4, whatever) unless they are the very very very expensive ones that use more than a tiny speck of platinum in the electrode. (Which you just about don't find in any parts stores, BTW.) The quality control on the regular platinums is sub-standard, and they have caused all manner of problems in several cars I know.

You can't go wrong with Bosch supers or NGK. The heat range depends on a few things like how you drive it. From what I know the platinum plugs are intended for modern ingnition systems. Of course I don't realy go for all of the special plugs with 4 electrodes or whatever (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

Flaps dude says that NGK uses a 4 digit number to identify their plugs now. Cross referened on the NGK site as 7432.

So does Bosch, but the parts house should still have the cross referance. If they don't they suck because the old numbers are still used all of the time.

I worked at Bow-Bow for a while after highschool (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) good times

Everything from non-functional plugs ("hey, it looks perfect, but it just doesn't spark!") to mysterious no-starts ("it started fine yesterday!) to the little platinum speck coming out of the plug ("is there supposed to be something there?") to the ceramic fracturing inside the combustion chamber.

That last one cost a buddy of mine a 944 engine. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) He "thought" he had fished all of the pieces out, but one got stuck between the piston and the cylinder surface. Drove it for a bit, and it wound up breaking the cylinder wall!!!!

I decline to state how many of these problems have occured to my 914s over the years. (Sometimes it takes me a while to learn, sadly!)

my problem with Bosch platinums was poor performance, switched back to the copper Bosch, and the probelms went away. Why I do not know, but I have experienced it. The platinum plugs "looked" fine but didn't work well.
