When you start turning up the power on your S55 or S58, oil temps climb fast. A few hard pulls, a hot lap session, or a long canyon run and you can feel the car working harder than it should. The CSF High Performance Oil Cooler keeps temperatures in check so your M3, M4, M2 Competition, X3M, or X4M stays strong and consistent. More stable oil temps mean more confidence leaning into boost, holding gears longer, and driving the car the way it was meant to be driven.

CSF developed this cooler after seeing more and more owners push the limits of their platforms. Real world track testing and data logging showed where the factory unit started to fall short once power levels increased. Using advanced condenser technology and optimized core design, CSF engineered a solution that improves cooling efficiency by around 30 percent while maintaining factory like fitment and airflow management.

Precision Engineered Design

Built using CSF AC Condenser Technology with a 1 row super high pressure 32mm 10 channel microtube for optimal oil flow and maximum surface area contact. The 32mm thick core provides about 15 percent more core volume compared to the OEM 28mm core. Features 5.4mm tall multi louvered fins for improved heat transfer efficiency. Utilizes OEM style inlet and outlet connections along with factory top and bottom rubber seals to ensure proper airflow through the ducting and shrouds. Includes a removable and replaceable rock guard to protect against road debris and an oil spill scenario. Direct drop in fit with no modifications required and includes mounting hardware.

Configuration Options

Single high performance oil cooler configuration designed as a direct replacement for the factory unit. Compatible with aftermarket skid plates and oil cooler guards including popular options from Fall Line and Turner Motorsport. Retains factory mounting location and ducting for seamless integration.
