Search through some of the "My engine runs like crap" threads. You'll find a lot of them were fixed by simply going from platinum to copper plugs.

By far the best plug I have used on a 16v is the Bosch WR8DS - I just pulled a set that were in for the last 12 years .... and they look nearly new with no errosion of either electrode: the 'S' stands for Silber = silver - and is a recommended plug in Porsche literature.

I ran the W7DRS in my 32v with equally good results.

Both plugs are still available, but maybe a bit more expensive than the platinum versions .... but they work.
