Oil Cooler

BMWs use an external oil cooler to regulate the temperature of engine oil and prevent a breakdown in viscosity and lubrication characteristics. If yours has suffered damage or developed a slight leak, make sure to replace it and keep the engine oil where it is supposed to be. Keeping this system properly serviced will significantly improve performance and increase engine life.

Upgrade your stock oil cooler thermostat for improved performance. Swap your factory 110-degree Celsius thermostat for a new 70-degree Celsius version for faster oil flow and extended temperature control. With oil temperatures reaching 230 degrees Fahrenheit by the time your factory thermostat opens, initiating oil flow at lower temperatures proves more effective than attempting to cool down already elevated temperatures.

Utilizing a factory-style thermostat, this upgrade can be used in all weather conditions and allows your engine to warm up properly, unlike thermostat bypass kits.

Kit contents:​

Lower temperature thermostat - 70c (158F) vs Factory 110c (230F)

An industry-leading reputation and overwhelming success with BMW cooling has made CSF the #1 cooling choice for the B58 power G2X M340i/M440i and G42 M240i. CSF continues to lead the way in G2X/G42 cooling, adding another product to the best-selling B58 cooling suite. With many motorsports teams and race enthusiasts now pushing over 1000 horsepower, the B58 is seeing oil temperatures well above normal. Once oil temperatures pass a safe limit, the G2X/G42 will go into limp mode. Needless to say, this can ruin a race, track session, or your overall driving fun in general. CSF is here to keep your B58 running at peak performance.
