The BMW M3 Oil Cooler by CSF is engineered for race enthusiasts who demand the best in performance and reliability. This Race-Spec Dual-Pass oil cooler is specially designed for the `00-`06 models, offering a robust solution for maintaining optimal engine temperatures during high-intensity driving.

Diving deeper into its construction, the CSF oil cooler utilizes a Bar & Plate design, enhancing its endurance against debris and high-speed impacts compared to the typical tube and fin structures. The extruded end tanks further solidify its resilience, ensuring that it outperforms the standard OEM options. Crafted for a seamless bolt-on experience, this cooler is compatible with the factory radiator or CSF High-Performance Radiators, requiring no modifications — a true "Drop-In Fit" application.
