EMP Marine Oil Filter 35-57803, Replaces 18-7879-1, Fits V6 4.3L Sterndrive and Inboard Engines

The EMP 35-57803 is a marine oil filter engineered as a direct replacement for the 18-7879-1 filter used across a wide range of V6 4.3L sterndrive and inboard marine engines. It is designed to trap combustion byproducts, metal particles, and other contaminants from engine oil as it circulates, protecting bearings, cylinder walls, and other close-tolerance components from abrasive wear. Keeping a clean, correctly-fitted filter in place is one of the simplest ways to extend engine service life and maintain consistent oil pressure.

This filter is built for engines specified to run 25W-40 FC-W marine oil at a 4.3 to 4.5 quart capacity, matching the lubrication requirements of the V6 262/4.3L through V6 267/4.3L engine families it covers. It threads on in place of the original filter using the same mounting interface, so no modification is needed during routine oil changes. Boat owners and marine technicians use it as a scheduled maintenance item alongside oil changes to keep engines running clean and reliable through the season.

Note: V6 engines equipped with the oil filter relocation option use a different filter (18-7824-2) and are not covered by this part number.
