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.

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 G8X M3/M4/M2. CSF is leading the way in BWM G8X (S58) Cooling and adding another product to the Power Cooling Package. Now CSF is pleased to announce the release of its BMW F8X M3/M4/M2C High-Performance Engine Oil Cooler. The new CSF Engine Oil Cooler is a great addition massively successful G8X Cooling Suite. Like the other cooling systems on the G8X, the factory oil cooler does a pretty good job in stock form. However, once you start adding a lot of power and pushing the car in aggressive driving conditions, the factory systems start to show its limitations. As more and more owners have pushed the limits of their S58, CSF is here to keep them cool. When designing this new cooler, CSF wanted to ensure the best possible performance with factory-like fitment. This oil cooler is a truly unique design using CSF’s AC Condenser Technology. The 1-Row Super-High Pressure 32mm 10-Channel Microtube provides optimal oil flow and maximum surface area contact. By keeping the factory mounting location and relative dimensions, the factory ducting and shrouds are all reused with no modifications necessary. In addition, CSF added a rock guard to keep the cooler safe. You’ve no doubt heard horror stories about an OEM cooling getting punctured and spilling oil all over the road or track. Now you can feel safer and more confident that your oil system is safe from road debris. With many motorsports teams and race enthusiasts now pushing over 800 horsepower, the S58 is seeing oil temperatures well above normal. Once oil temperatures pass a safe limit the G8X 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 S58 running at peak performance. Features: 8mm Tall Multi-Louvered Fin vs. OEM 6mm Made with CSF’s AC Condenser Technology Using a 1-Row Super-High Pressure 32mm 10-Channel Microtube for Optimal Oil Flow and Maximum Surface Area Contact Utilizes OEM Top/Bottom Rubber Seals for Optimal Airflow OEM Style Inlet/Outlet Connections Drop-in Fit Requires No Modifications to Install 2-Year Limited Warranty Ideal for Road Racing, Drag Racing, and Vehicles With Increased Performance Applications: 2022+ BMW G87 M2 (incl. Competition) – 6MT & ZF8 Auto 2021+ BMW G80 M3 (incl. Competition) – 6MT & ZF8 Auto 2021+ BMW G82/G83 M4 (incl. Competition & CSL) – 6MT & ZF8 Auto 2022+ BMW G81 M3 (incl.

The E36 Euro Spec Oil Cooler is exactly what it sounds like. E36 M3’s in Europe came equipped with an oil cooler that mounted under the radiator and was a popular upgrade for E36 owners in the US. Unfortunately, BMW discontinued the oil cooler and they have become harder and harder to find. BimmerWorld reached out to CSF to design a replacement unit that would fit exactly like the factory unit but perform even better. The original oil cooler used Tube and Fin construction. While this is acceptable for cooling performance, it is not a very robust design. CSF chose to go with a Bar and Plate construction to improve durability. While there is plenty of ground clearance, the cooler is low enough to see some potential abuse on the track. CSF wanted to offer that extra durability of a Bar and Plate cooler for track enthusiasts and those running their car on the lower side. The CSF Oil Cooler was designed to be a 1 to 1 replacement for the OEM unit in terms of fitment. This means it uses the same OE mounting points, hardware, and lines. For a Euro E36 M3 or US Z3M, the oil cooler will be a drop-in fit installation. E36 models that were not equipped with the oil cooler from the factory will need the BimmerWorld Euro Oil Cooler Bracket Kit which can attach to an OEM spec Radiator or the CSF #3054.
