HEy guys. I'm running NGK BPR6eix-11 iridiums and they seem to have built up some white deposits. I gapped my plugs to .28 I understand the cause of this could be caused my a lean mixture, overheating, or advanced timing or something. Please tell me what i need to do. oh yea, my car is 100% stock besides the 60-1 ct26 running stock boost. thanks
