my plugs always look fine, it must be my great tuning skills ::)

oops just checked the plugs they are PN: 5632 (BCPR6E-11) the other ones are one heat range colder (there for a 90 teg)...

Well if you have problems with detonation you can go colder, but just run the stock heat range and pull them every few thousand miles and check them, if theyre glazed or somthing you might have to go colder. "

Hmmm I'll do that
Thanx
