Aluminum Valve Adapter for Mercedes-Benz OM611 OM612 OM647 CDI Engines

Proper airflow improves throttle response in heavy diesel engines. This aluminum valve adapter replaces restrictive stock fittings on OM611, OM612, and OM647 CDI blocks. You can mount it easily during air intake upgrades. The design fits C, E, S, Viano, and Vito chassis handling 2.2 liter and 3.0 liter cylinders. Precision machining ensures a clean seal. Lightweight metal cuts down minor rotating mass.

Pull more power from your existing turbos using careful setup habits. Clean the mating flange before placement. Apply a measured amount of oil resistant adhesive to stop vacuum leaks. Verify bolt tension gradually to protect fragile threading. Regular inspection after break-in periods maintains consistent cylinder scoring.

Part Numbers: Accurately replaces A 646 140 08 60 and A 646 140 17 60.
