Hi guys im looking at getting some NGK plugs for my scooby 04 STI, looked on the website and just want to make sure I get the right ones. Not sure if its the ngk pfr6b spark plugs or the ngk pfr7b spark plugs can anyone give me any clues please?

 

I'd say 7b's for an STi especially if tuned

 

CAR IS STANDARD BUT LOOKING AT A FEW MODS OVER THE NEXT MONTH OR TWO.

 

ngk 7's is in mine.
