I pulled My sparked plugs the other day to change them and found that They were Two diferent colors. One side looked like it was rusted and the other side was BLACK. Colors split exactly in half. They all smelled like gas. I knew the car was running rich but, I didn't know it would turn spark plugs two different colors. The gaps were at about .035" I have A blaster coil, Moroso wire, Accel Cap and rotor. ANyoine kow what this could mean???

Thanks,
Lars

Are you using any fuel additives, such as 104+ octane boost? if so it'll cause the plugs to turn a red/rust color.

 

Sure have been. I've been using NOS Octane boost. Not quite sure why. But i Have been. Thanks for the quick info.

Later,
