CSF 07-13 BMW M3 (E9X) Race-Spec Oil Cooler

CSF’s engineering expertise shines through in the design of this Race-Spec Oil Cooler, built to keep your E9X M3’s engine oil temperatures under control during aggressive street driving or track sessions. Maintaining optimal oil temperature is crucial to protecting your engine from overheating, which can lead to performance-limiting "Limp Mode" activation in modern vehicles.

Older cars lacking these systems risk severe engine damage from excessive oil heat, making an effective cooler an essential upgrade.

This CSF oil cooler is designed to mitigate the risks of oil overheating by efficiently dissipating heat and maintaining stable operating temperatures under extreme conditions. Whether you’re pushing hard on hot summer days or competing on the track, this cooler ensures your engine oil stays within safe limits, preserving performance and reliability. Don’t let high oil temperatures spoil your drive or damage your investment — trust CSF to provide durable, race-proven cooling solutions for your E9X M3.
