BMW 1M / 135i E82 and 335i E9x N54 Aluminium Coolant / Thermostat Hose Adaptor

The hose connecting the engine block to the thermostat on the N54 engines is equipped from factory with a plastic adapter, known for its fragility and poor thermal resistance. In order to improve the reliability of the cooling system on the BMW 135i E8x and 335i E9x (N54), Alpha Competition offers this aluminum adapter, much more resistant, helping to avoid breakages too common with the original one, while also optimizing flow transfer with its exclusive smooth flow design.
