Hey Spayne,

T.C.
According to a how to read your plugs, the yellow is not good:
High Speed Glazing
APPEARANCE: Glazing appears as shiny coating on the plug, either yellow or tan In color.
CAUSE: During hard, fast acceleration, plug temperatures rise suddenly. Deposits from normal combustion have no chance to fluff off; instead, they melt on the insulator forming an electrically conductive coating which causes misfiring.
RECOMMENDATION: Glazed plugs are not easily cleaned. They should be replaced fresh set of plugs of the correct the condition recurs, using plugs with a heat range one step colder may cure It.
