Even in stock trim, the oil gets hotter than you might expect. Add additional horsepower and stress on the engine by running it around the track for just 10 minutes straight, and the oil gets extremely hot. Even the best synthetic oils should be kept under 250°F if possible and never above 300 degrees, yet the stock N55 cooler just won't get the job done.

CSF's high-performance, race-spec oil cooler will keep oil temperatures stable, even in the most demanding endurance racing conditions and extreme ambient temperatures. This CSF M235i/335i/435i oil cooler has been lab tested in an ISO-certified, state-of-the-art cooling system testing facility that includes wind tunnel, vibration, thermal cycle, burst pressure, and salt spray corrosion testing for maximum performance and reliability.
