How exactly should plugs look when FI? Reason being is mine are mainly black with a little bit of white on the porcelin and some gray on the insulator. I've seen all the plug sites with descriptions etc. But how do most of you guys with turbo hondas plugs look?

that sounds fine.

my plugs look WHITE cause i run lean at part throttle to get good gas mileage.

not 'white' but 'aluminum' colored specks.... these would be made from aluminum that is now missing from the pistons.

A plug that's gone through detonation typically looks like you ran it through a garbage disposal. I have a plug at home from my '93 GS-R that had alot of blow-by in #4, and there was some serious detination in there that utterly decimated the plug.

Greyish-white is fine, the super bright white insulators with blisters and aluminum specks are what you want to avoid.

hrm so my flat white is ok. See I was under the impression any light grey and white was a sign of leaning out. Needless to say I dont boost much untuned what so ever. But I havent now in like 2 weeks because it bugged me out. Goin to get tuned next week tho.
