Heater Core Coolant Block-Off Plate | M50 M52 S50 S52
The factory cylinder head on US-spec M50, M52, S50, and S52 engines includes a rear coolant outlet for the heater core. When deleting the heater core on a dedicated track car or converting to Euro-style coolant plumbing, this outlet is no longer needed.
Our Heater Core Coolant Block-Off Plate provides a clean, reliable way to seal the rear cylinder head coolant passage. Precision machined for a direct fit, it replaces the factory heater hose connection while simplifying the cooling system and eliminating unnecessary coolant plumbing.
The kit includes a genuine OEM gasket and all required installation hardware for a straightforward installation.

- Seals the factory rear cylinder head heater hose outlet
