hi do u no the diff between 6bs and 7bs iv been told to try them both, cheers kev

std car uses pfr6b's, fine for std boost, etc................if the car is at all modded we tend to fit/recomend pfr7b's, colder running plug (copes with higher temps easier) will have no impact on day to day running.................
