Hey Guys,
Im just curious as to what bigger gapped plugs would do on a fairly stock engine (poddy, 3inch cat back, 2 way).
Change my plugs today and the old ones had a larger gap.
I had a misfire problem that was really intermittent, happen once a year ago and once 2 weeks ago (sounded like WRX, lacked power, once turned off and started a few times it fixed itself). Have Spitfire coilpacks in also, which i only realised today
