CSF High-Performance 2-Row Aluminum Radiator for Select 1988-1999 BMW 323/325/328/M3 #3054

Fits select 1988-1999 BMW 323i/is, 325i/is/iX, 328i/is, and M3 (E30/E36 chassis).

Reliable thermal management is critical for BMW engines, especially those subjected to track use or high-horsepower street builds. The CSF 3054 High-Performance Radiator replaces the failure-prone factory plastic-tank units with a heavy-duty, all-aluminum design. Engineered for a true drop-in fit, this radiator utilizes CNC-machined "Quick-Connect" inlet and outlet connections and mounting brackets to ensure it accepts all OEM components, including hoses, fan shrouds, and the AC condenser, without modification.

The core features CSF’s proprietary B-Tube technology. Unlike standard oval tubes, these B-tubes are seam-brazed and shaped to increase the heat transfer surface area by approximately 15%, providing the cooling efficiency of two smaller tubes within a single 42mm space. Paired with ultra-efficient 6.5mm multi-louvered fins, this design maximizes airflow and heat rejection even in demanding motorsports environments.
