If you've experienced rising oil temperatures during spirited driving, track days, road course events, or high-horsepower tuning, the factory oil cooler can quickly become a limiting factor. The CSF High-Performance Engine Oil Cooler was engineered specifically for BMW's Gen 2 B58-powered platforms to deliver increased cooling efficiency, improved thermal stability, and greater protection under demanding driving conditions.
Utilizing CSF's motorsport-proven cooling technology, this direct-fit upgrade features a high-pressure microtube core design and increased core volume to improve heat rejection while maintaining factory fitment and reliability. The thicker core design provides approximately 14% greater cooling volume compared to the OEM cooler, helping reduce oil temperatures and combat heat soak during extended performance driving.
Whether your BMW is a daily driver with bolt-on modifications, a dedicated track car, or a high-horsepower street build, maintaining consistent oil temperatures is critical for engine longevity, power consistency, and protection of your B58 engine.
