|  Spark plug reading with water/alky injection?
Hi everyone, Has anyone noticed abnormally clean, WHITE ceramic on thier plugs from injection? I just checked my plugs the other day and while the actual electrode part was in good shape, the ceramic around it was almost brand new color white, with a little tiny bit of a tan spot on some. So am I running hot/lean? Or are these this clean because of the spray? ~Dan |

It's just clean from the alcohol, I pulled mine once a month and they always looked like that. The lack of carbon build up keeps them looking like that.

great news! By the way, Im only spraying water/washer fluid right now, but Im thinking the same principle applies, right? So how do we know when we are getting lean? White center electrode? Whitening ground? Thanks! ~Dan |

That's all I used unless I was going to the track. The water injection will mask most spark plug reading so a good wideband or 02 monitor like scangauge or LS1M comes in handy.
