Reading spark plugs
Reading spark plugs
Hi, I noticed the exhaust tip was white coloured at the end of my last race in the fiesta st at knockhill, but all the other cars looked quite black. I thought I d check the plugs which also have a white colour to them. Ive spoke with the people who flash the ecu who seemed to think it was a sign of a well performing engine. Should they not be more of a coffee colour?

That looks like a good plug in my book but I'm no expert.

Thanks for advice. Good to have a second opinion.
