Sierra 18-8700 Oil Filter (Marine Aftermarket)

Description

The Sierra 18-8700 is a marine aftermarket spin-on oil filter, a direct replacement for the equivalent outboard OEM filter.

Why it matters

Engine oil picks up combustion soot and fine metal wear particles, and the oil filter is what keeps them out of the bearings, journals and turbocharger. Fitting the correct filter means the bypass valve opens at the pressure the engine was designed for.
