spark plug gap on a boosted car


Recommended Posts

well you book says something like .045 but I run 8 PSI and I set mine for .040. you want to go with a colder rated plug for you car and a smaller gap. I heard up to 10 psi take off .005 and 10 psi and up take off .008 and that is the lowest you go.


but ya. I would for yours is gap it at .037
