andrew3160 Posted February 19, 2012 Report Share Posted February 19, 2012 If I remember correctly, I am running the same setup with slightly colder plugs, BR8ES. What's your timing at and what octane fuel are you running? I am at +4 timing and 91 octane fuel with no issues. Quote Link to comment Share on other sites More sharing options...

Coupelx Posted February 19, 2012 Report Share Posted February 19, 2012 br7 is a hotter plug. that is why you are backing them out. BR8ES is the correct plug for non resistor wire caps and B8ES for resistor caps. Quote Link to comment Share on other sites More sharing options...
