And the right NGKs are the *only* way to go. I'll bow out to the more eloquent explanations from the others here who actually know *why* ... You're right though - non-NGKs in a C900 are pants! And that's a fact! I run the cooler T16 type plugs in my T8 (BCP7EV) and she just loves 'em. She's slightly uprated though 8) At over 4 quid each, they're expensive, but last for 25-30K miles! I gather they're now called BCP7EVx or something ... It's been a while since I had to buy plugs :) Paul 1989 900 Turbo S http://saab.go.dyndns.org/
