Am now back on trusty 071's gapped @ 0.65mm and was on full boost all the way home with my cock in my hand! No problems what's so ever.
071's all the way! No need for any others ðð Poweeeeer!
Happy days
I had so many people telling me when I first got my Cossie to run denso and all sorts of other make plugs, they all made it run like a bag of shite so I went back to standard ford plugs and I haven't suffered a single misfire ever since! Only when it does start to misfire at least once a year I know it's spark plug change time and then it's good for another year at least lol!!
