Mercury 35-866340K01 is a genuine marine oil filter for MerCruiser sterndrive and inboard GM gasoline applications. Published fitment lists it for MCM/MIE GM gasoline engines except V6 models with the oil filter mounted on the engine block, and also lists 4.5L and 6.2L Mercury engines. The filter is built for marine service with stronger construction and corrosion-resistant coating compared with a standard automotive filter.
