Turner Motorsport M52TU/M54 Mechanical Thermostat Conversion

The factory E46 thermostat housing is a combined unit featuring a plastic housing and a built in thermostat that you cannot replace separately. These plastic all-in-one units are commonly know to crack or fail causing a headache. This unit not only converts your plastic housing into a billet aluminum unit that will not crack but also swaps out the integrated thermostat for a replaceable thermostat. The ability to swap out thermostats separately from the whole housing opens up doors to changing thermostats to different temperature ratings based on your application while also providing lower maintenance costs. The days of buying full replacement thermostats are over!

The billet housing is designed to be utilized with E46 M3 upper and lower radiator hoses and also features -16 ORB connections for custom radiator hoses. A supreme upgrade from the factory and aftermarket plastic units this thermostat housing kit can be used for the smart daily driver or the track hero who wants to ensure the durability of their cooling system.
