Aluminum Thermostat BMW M47 / M57 – Opening Temperature 80°C

The ultimate upgrade for your BMW engine cooling system! Unlike the stock plastic housing that becomes brittle over time and fails under pressure, this thermostat is made from high-quality aluminum, guaranteeing maximum durability and zero coolant leaks.

Designed to open at 88°C, it ensures your engine operates at ideal parameters, protecting internal components from overheating and optimizing fuel consumption.
