    • Works alright. Runs a little hot.
The original one opened up around 96 to 97°C, this one opens up at around 99°C. Makes bleeding the system a little nerve-racking because it tickles 103°C while bleeding, afterwards it works as normal. The electronic heating element that opens the thermostat under full throttle works as it should.

    • Go OEM
Looked awesome and seemed like a genuine good deal but after installation I had leaked large amounts of coolant from the seal. Would not purchase again, Go OEM!

    • Creates grounding issue
Got sick and tired of all the plastic on my M54 engine, so replaced the valve cover, thermostat, and radiator with all aluminum versions. The other two worked well, a Mitzone valve cover (same brand as this thermostat) and a Mishimoto radiator. But this all aluminum thermostat housing is different. The M54 uses a kind of wax heater on the thermostat, and depending on that it sets the thermostat open or closed. Very specific voltage resistance. With the aluminum housing, it throws it completely off, resulting in a engine code that essentially puts the cooling system in a MAP mode. Keep the thermostat a plastic oem brand, no issues. But like I said, the aluminum valve cover from this company is a legitimate upgrade with good quality. ... show more
