Note for M4 GT4: this is the standard thermostat, the same as the standard road car. There is also a endurance-spec thermostat bypass that requires additional lines and cooler to be fitted. Alternatively the BimmerWorld DCT Diverter Valve can be used to accomplish the same bypass in a stock thermostat housing.

This is a Genuine BMW transmission thermostat with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
