M50, S50, S52 High Performance Thermostat Housing Cover

M50, S50, S52 High Performance Thermostat Housing Cover

Swap plastic for aluminum. And forget about cracking, forever.

Here are your choices: you can wait for the plastic factory thermostat housing cover to break and cause major overheating. (Even with a new stock cover, it won’t take long.) Or you can install a thoughtfully engineered all-aluminum thermostat housing cover from Active Autowerke and never experience this type of failure again. Sure sounds like a no-brainer to us…

Forged to exact factory tolerances, this unit is a true easy bolt-on – especially suited for racing or load conditions like heavy traffic, where engine temp can rise rapidly. The housing is guaranteed never to break from overheating or over-tightening, and its CNC machined surface ensures a precise seat.

Unit comes complete with a new sealing gasket; a new thermostat is recommended but not included.
