Improve engine oil temperature control with the CSF 8032 Race-Spec Dual-Pass Oil Cooler for the BMW E46 M3 and E39 M5. Developed with Rogue Engineering, this direct-fit upgrade replaces the factory single-pass cooler with a top-to-bottom dual-pass design for increased flow path and cooling surface area. Its TIG-welded extruded end tanks, heavy-duty bar-and-plate core, and high-density multi-louvered fins deliver a durable cooling solution for demanding street, track, and high-performance BMW builds.
