Think about it...ALL that carbon being burnt off. Think it's doing any good for the plugs?

Oh little Judgeypoo, how I've missed that face of yours!

I guess when the car is past the 75K range, or if the car is getting bad gas mileage.

I pulled the plugs from the Phoenix after I seafoamed it. It was the first time I seafoamed the engine through the vacuum lines and there was negligible carbon buildup on the plugs. I don't recall the miles on the plugs but I know I was due for a swap


Judgeypoo is looking good!
