Hi People, Just a quick question, Just picked up some Bosch FR 7 DPP+ Spark plugs and the Gap on them are 0.7mm. What should the Gap be for my Renault Megane 225 F1 Team engine 2006? I think the other spark plugs in the engine are currently 0.9mm Should i re-gap them upto that size? Cheers Again
never had to gap mine either. you were probably best sticking with NGKs rather than bosch as i dont think they are highly recomended
