CSF 00-06 BMW M3 (E46) Race-Spec Dual-Pass Oil Cooler

The CSF x Rogue Race-Spec Dual-Pass Oil Cooler is engineered with a rugged Bar & Plate construction in a top-to-bottom configuration, delivering superior durability and performance. Unlike traditional tube and fin designs, the Bar & Plate layout enhances strength and resistance to damage from road debris and high-speed impacts, making it ideal for track and street use alike. The inclusion of extruded end tanks further boosts structural integrity compared to the OEM’s bent aluminum sheet construction, providing long-lasting reliability under demanding conditions.

Designed for easy installation, this cooler bolts directly onto the factory radiator or can be paired with CSF’s High-Performance Radiators specific to the E46 M3 (#7058) or E39 M5 (#7064). It utilizes the stock oil cooler lines, allowing for a straightforward, no-modification setup that ensures optimal oil cooling efficiency during aggressive driving and racing scenarios. This unit represents a robust upgrade for enthusiasts seeking enhanced engine protection and thermal management.
