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 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 EU E36 M3 or USMD Z3M the oil cooler will be a drop-in fit installation. E36 models that were not equipped with the oil cooler from the factory can use the BimmerWorld Euro Oil Cooler Bracket Kit which can attach to an OEM spec Radiator or the CSF #3054.
Product Details
Design & Engineering
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 which can stand up to far more abuse.
The "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.
CSF vs OEM
CSF #8301
BMW #17212244084
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 EU E36 M3 or USMD Z3M the oil cooler will be a drop-in fit installation. E36 models that were not equipped with the oil cooler from the factory can use the BimmerWorld Euro Oil Cooler Bracket Kit which can attach to an OEM spec Radiator or the CSF #3054.
Installation Options
While the oil cooler is a bolt on upgrade for the Z3M and Euro Spec M3, most owners will need some extra bits to install an oil cooler. There are a few different options when it comes to adding the oil cooler to your E36.

Aftermarket Parts and Custom Lines
The other method for installing an oil cooler kit on your E36 is by using an Oil Cooler Cap. These caps bolt onto the filter housing with provisions for connecting oil lines similar to a sandwich plate. This allows you to connect standard -10AN lines for your custom setup. One of these Oil Cooler Caps paired with the CSF #8241 -10AN Fitting Adapter is the most cost effective way to add the CSF Oil Cooler.
