CSF Bmw E46 M3 / E39 M5 Race Spec Dual Pass Oil Cooler

The CSF Race-Spec Dual-Pass Oil Cooler for the BMW E46 M3 and E39 M5 is engineered to address the shortcomings of the factory oil cooler, which often struggles under high-performance driving conditions. While the OEM cooler may suffice for daily driving, it quickly proves inadequate on the track, leading to dangerously high oil temperatures that can jeopardize engine health. In collaboration with Rogue Engineering, CSF has developed a superior oil cooler designed to withstand the rigors of track use while ensuring a straightforward installation process. This high-performance oil cooler is over two times larger than the factory unit, boasting a volume of 243 cubic inches compared to the OEM's 103 cubic inches. This significant increase in capacity allows for cooler and more consistent oil temperatures, even during intense driving sessions on the hottest days. The CSF x Rogue oil cooler features a robust Bar & Plate construction, moving away from the traditional tube and fin design. This top/bottom configuration enhances durability, making it better equipped to endure impacts from debris at high speeds on both the road and track. Additionally, the use of extruded end tanks provides a stronger construction compared to the bent aluminum sheet design of the OEM unit. Designed as a bolt-on upgrade, this oil cooler seamlessly integrates with the factory radiator or CSF High-Performance Radiators (E46 M3 - CSF #7058 / E39 M5 - CSF #7064), utilizing the existing factory oil cooler lines for a hassle-free installation. For BMW enthusiasts looking to elevate their performance and protect their engine during high-stress driving conditions, the CSF Race-Spec Dual-Pass Oil Cooler is the ultimate solution, delivering unmatched cooling capacity and reliability.
