Is this common? I am going through a set of spark plugs after each weekend of use. That is roughly 30 to 40 gallons of race gas run through the motor and seems to be about it. Don't get me wrong the motor still runs and anything above 3000RPMs is fine but motor stars missing in the low rpm range. A new set of spark plugs seems to solve this and the motor runs crisp again. We do run it very hard and are running 20lbs of boost. I have run NGK B8ES, B8EV, B8EG, BR8EQ, BR8EIX PLATNIUMS even the 40 dollar each 105s or 115s. My favorite plugs are BUR9EQS for both the leading and trailing. These are the ones that have the X cut into them. I pay as low as 6.50 for them if I can find them at Kragen auto parts. Racing Beat has them for 9.50 and I get them there if i cant find them else where.

I was having problems with those cheaper paper over metal turbo gaskets blowing and burning up at about the same time and thought the motor was sucking the burnt up gasket material into the housings when letting of the throttle and coating the plugs with it causing them to foul quick.

I have since switched to the stainless steel embossed turbo gaskets and the plugs don't seem to last that much longer so I am confused now.

Does anyone else chew through spark plugs as fast as me? Is this boost related? Less boost more plug life?

The plugs don't seem black or white. They seem to have that anodized coating burned off them. They don't seem like before when I had the turbo gasket issue like something foreign is embedded on them.????
