I use the standard Bosch Platinums in my 86 951 and I am very happy with them. Out of the box though the gap was off from the factory setting, so I bought a gapper and gapped them. Even running 17psi, I have not heard a hint of detonation. I've always used Platinums in all of my cars, including about 5 Saab turbos I've had over the course of the past 10 years. I think I tried an Autolite or something like that in a tricked out turbo convertible I had and the bottom of the plug actually blew right off into the cylinder! Since then, I have never bought a different type of plug on my own free will. Good luck,
