Just wanted to pick the brains of the various member on the boards. Did my spark plug change yesterday after having some insane engine sputtering, all is well now though. I do have a picture to show everyone and am looking for some insight.
Since I'm not aware of the cylinder numbers, I just labeled them from order of removal; passenger to driver side. My driver side plug is insanely black compared to the first three.... Why is this?
Yes, I am running ethanol, E30 to be exact. Tuned pretty aggressively, no need to disclose the tuner, I feel that is irrelevant. The plugs in the picture are NGK and lasted 16,xxx miles, damn near 2 1/2 years.
