CSF 00-06 BMW M3 (E46) Triple Pass Radiator

The CSF High-Performance All-Aluminum Triple Pass Radiator for the 2000-2006 BMW M3 (E46) is built for serious cooling performance, whether on the street or at the track. Designed for high-horsepower builds and motorsport conditions, this radiator utilizes CSF's proven Triple-Pass Flow Structure, forcing coolant across the core three times for significantly reduced outlet temperatures and maximum cooling efficiency.

A 2-row core with CSF's exclusive B-Tube Technology increases strength while delivering up to 15% more heat transfer surface area than traditional designs. Lightweight aluminum construction and ultra-efficient, multi-louvered fins further optimize airflow and heat dissipation. Wind-tunnel tested for maximum performance, this radiator provides race-proven cooling reliability with a perfect fit for the E46 M3 platform.
