I have used Bosch platinums and the new 4 post platinums in my 80 Euro for many years with great success. But now that I have an M6 with the S38 engine I am having a hard time finding a more modern plug to replace the X5DC stock spark plugs for the S38 engine. Has anyone found a modern plug that works?

I'd contact Steve Haygood and go with whatever he recommends...
