All-Aluminum Radiator 2-Row 42mm Core

The CSF #3054 High-Performance All-Aluminum Radiator is engineered for BMW E36 M3, 3-Series, and E30 3-Series vehicles, offering superior cooling for both street and track applications. With over five decades of manufacturing experience, CSF provides a reliable solution for high-horsepower builds and demanding motorsports environments. This radiator utilizes a 2-row, 42mm core featuring CSF's exclusive B-Tube Technology. Unlike conventional oval tubes, CSF's B-tubes are brazed over a seam, creating a stronger and lighter design that increases heat transfer surface area by approximately 15%. This results in dual liquid laminar flow and enhanced cooling efficiency. The core is further complemented by ultra-efficient, multi-louvered fins, precisely aligned to maximize airflow and heat rejection, validated through wind-tunnel testing. The unit features OE-style brackets and fittings that are CNC machined and welded for superior durability. An all-aluminum race-style drain plug is included for convenient draining. This radiator is specifically designed to fit a range of BMW E30 and E36 models, including the 323i, 323is, 325i, 325is, 325ix, 328i, 328is, and M3 (both 3.0L and 3.2L engines). It accepts all attaching OEM components, including quick-connect hoses, the AC condenser, mounting brackets, and fan shroud.
