Hi. Got one of your TSR Snetterton 2l 16v engines. There is a stamped ali plate by breather that says AALR 715 if that helps. I'd like to know what spark plugs you recommend for this engine. The ones in it are Bosch Super 4 F56's from what i can make out. I have not had alot of luck trying to cross ref' back to NGK. It's primarily a track car if it makes any difference. Cheers Dave
