Domestic Coil-on-Plug (COP)

OE Design Failure:  Engine design allows moisture into the spark plug wells, causing corrosion, oxidation and shorts.

CARQUEST Design:  Specially formulated marine-grade grease is utilized during assembly (also included in box).

CARQUEST Advantage:  Helps prevent moisture and contaminants from eroding coil connections and internal components.
