i remember on the First SER.Net Dyno day back in 1999, the Bosch was dynoed back to back w/ the oem NGK platinum plugs - The Bosch platinums lost 1-2 HP compared to the NGK Platinums.

Mike K. - do you still remember the other plugs that where tested?

Tevs

Run PFR6B-11's and nothing else unless you are turbocharged or runing big NOS, then run PFR7B-11's.

Bosch Plats suck big ass, the worst plugs I have ever used.
