Maintaining higher oil temperatures reduces emissions at the factory power levels but puts your engine cooling at a serious disadvantage at higher power levels. This simple device lowers your oil temperatures by bypassing the factory oil cooling thermostat and allowing oil to circulate through your oil cooler full time. The result is dramatically lower oil temperatures and more consistent engine performance. Engine oil warm-up time is only marginally increased. Installs in minutes and is fully reversible.

The Burger Motorsports low temperature thermostats are CNC machined for a precise fit. Anodized red for protection. Engraved with the BMS logo. Made in The USA
I've had one of those in my car for the last week or so. I also have the BMW Performance steering wheel so I can monitor oil temps right from startup. I've noticed very little change in the speed the car warms up and peak temps have been reduced by 3 degrees.

Cheaper than a 1000 euro additional oil cooler from Alpina.

Evolution Racewerks do a replacement cooler which is highly recommended though.
