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.

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.

Designing the ultimate BMW E30 Oil Cooler was not an easy task. While with custom fabrication anything is possible, CSF prides itself on making upgraded products that fit like a factory unit. Fortunately, BMW already did some of the leg work for this in the late 1980s. The new CSF #8218 is based on the race-proven and championship-winning formula used by BMW. To give you some history on this topic, we have to go back to 1987. After BMW decided to enter Touring Car and DTM racing, they created what most would consider to be the ultimate E30 M3. In the span of about 5 years, the Group A spec M3 became the most successful touring car of all time. This race-spec BMW won two champion’s titles in the European Touring Car Championship and German Touring Car Championship (aka DTM) and countless other victories. The BMW Engineers had to design an oil cooler that could keep up with the added power of the race-spec engine and perform under the grueling conditions on the track. The size of the standard factory oil cooler was increased by about 50% while using the same mounts and connectors as the standard production M3. The CSF E30 Group A / DTM Race Style Oil Cooler is the same size as these race coolers with some modern upgrades/updates. While your original system may still be functional, it is likely not in the best shape. Dented, clogged, and weathered coolers just can’t perform like a new cooler. Even then, the old tube and fin design don’t compare to the durability and performance of a bar and plate design. CSF understands that most owners don’t want to change the look of their Bavarian classics at this point. That’s why the E30 Group A / DTM Oil Cooler was design to fit in the factory location with no custom mounting hardware necessary. The CSF Oil Cooler offers superior cooling capacity, modern technology, and costs less than a genuine OE replacement. When designing this new cooler, CSF wanted to ensure the best possible performance while ensuring the cooler was as durable as possible. As you’ve seen, oil coolers and other heat exchangers can take quite a beating over time. CSF utilizes an extremely rugged and durable Bar/Plate design that can stand up to far more abuse. The CSF “Aero-Flow” Bar design reduces weight compared to other Bar/Plate designs while maintaining maximum strength and air flow. These “Aero-Flow” bars improve heat dissipation with high-density turbulated multi-louvered fins. Turbulation increases the turbulent flow through a tube, effectively increasing heat exchange rates and abilities. At around 50% larger in size, the CSF #8218 Oil Cooler increases both fluid capacity and core surface area. The overall performance of the Oil Cooler far exceeds the factory cooler’s limits. 100% All-Aluminum construction ensures the best performance and durability. In addition, the black powder coat finish provides extra protection and offers an OEM look behind the grille of your E30. Features & Specifications: Group A / DTM E30 M3 Oil Cooler Design Direct fit oil cooler for BMW E30 M3 Can fit all E30 Chassis (see applications and fitment notes) High Efficiency & Rugged Durability Bar/Plate Design “Aero-Flow” Bar Lightweight Construction for Strength and Maximum Flow Cast End Tanks with 100% Tig Welded Construction Satin Black Finish for Extreme Protection Against Corrosion and Debris Comes complete with fitting kit for both OEM style as well as -10 AN male connections Fitment Notes: 1986-1993 BMW E30 M3 (S14) The long factory oil hard line will not be able to use support brackets on the back of the radiator. This is due to the adapter fittings pushing the lines out about a ½” from factory so the brackets won’t line up but the lines will still run to the proper location and can be connected. 1985-1987 (up to 09/87) BMW E30 325 w/ Factory Oil Cooler Requires custom lines (factory hard line passes over the oil cooler normally but this unit is too tall to run that line over the top). 1988-1993 BMW E30 325 w/ Factory Oil Cooler Requires custom lines & mounting hardware. E30 Chassis has provisions for OEM mounting hardware. OEM Mounting Hardware part number listed below. 1984-1993 BMW E30 3-Series w/o Factory Oil Cooler Requires lines, mounting hardware, and sandwich plate (or provision for oil hook up).

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.

The turbocharged E9X 335i is renowned for its excellent performance and the ability to custom tune for more horsepower. Unfortunately, it is also known for oil cooling deficiencies that can reduce horsepower output and potentially compromise engine longevity, especially when driven enthusiastically or when boost is increased. To help maximize the power of your BMW, this FTP Motorsport kit adds a second oil cooler behind the kidney grills in addition to the factory oil cooler. This not only increases the cooling capacity, but more than DOUBLES it! Our kit provides the factory oil cooler with much more airflow then what is available in the fender wells. Only for vehicles with factory oil cooler
