New N52 ECS Performance Coolant Outlet Hose Kit

Some of the biggest issues when owning a BMW can come from cooling system components. Failure is seen with the plastic fittings and adapters from years of hot to cold temperature fluctuation. The N52 engine sees failure at the plastic adapter connecting the thermostat hose to the cylinder head, this adapter simply shears off at the end of the barbed fitting.

Our engineering team decided a billet aluminum piece was a much better option to contend with the temperature fluctuation.


Much stronger part than OEM plastic
