I don't have doubt.. for high perfomance use, turbo or aspirated, in high CR/DR, the best is NGK B9EGV. 9 is cold spark, is good for prevent detonation(don't make a hot point inside of chamber).
Bosch Platinum series is good too, but is not maked especial for competition use like B9EGV.

I personally will be going for NGK Platinum next time i change them as ive heard good stuff about them.
Oh, and i spoke to NGK technical a few months ago, and they confirmed the DO NOT list a Gold version of the LET plug, only the Platinum or standard ones. HTH

Ok i went for the bosch`s what a difference its the best £40 ive ever spent the car doesnt miss a beat whereas before it was blowing out the spark as soon as it hit 14psi ive now turned the boost up to 17psi and its bloody scary, next step is rolling road to ensure fueling correctly then set boost at recomended 18psi!
