🔧 Product Description

Genuine MerCruiser Gen III MPI Upper Intake Manifold - Part Numbers: 885167 / 8M0097033

A genuine used upper intake manifold or plenum for GM-based MerCruiser 5.0L, 5.7L and 6.2L MPI marine engines.

The aluminium upper plenum bolts to the lower manifold and distributes air from the throttle body across the intake runners. Original part number 885167 has been superseded by 8M0097033 and is also identified by casting reference 8M4503517. Volvo Penta uses corresponding upper inlet-pipe number 3858958 on related engines.
