CSF High Performance Aluminum Racing Triple Pass Radiator CSF7058 compatible with 2001-2006 E46 M3

CSF uses new technology packed into a compact two-row design for better cooling capacity without the added weight. More efficient B-tubes have greater surface area for cooling (15% cooling capacity increase in fin technology alone) and a precision multi-louvered fin to increase heat rejection performance and surface area contact. Additionally, this CSF part has more total cooling tubes, and due to the efficient B-Tube shape, airflow through the core is improved as well. These technical features all contribute to improved cooling efficiency over OE-type performance upgrades, as well as other standard "performance" aluminum tanked radiators which are nothing more than aluminum tanks on a traditional stock core.Made in Indonesia in the same factory that produces CSF parts for aftermarket and car line production for several European cars. This part is a much higher level of quality than the typical Chinese factory parts. All CSF radiators come with a two year warranty against defects in craftsmanship.Key Features: Mirror Polished Finish,Precision 'SAE Standard' Filler Neck (Standard Caps Available),Drop-In Fitment Requiring No Modifications,OE Specific Mounting Location,Pressure Tested at 50% Higher Pressure Than OE Units,40% Higher Burst Strength Over OE Units,All Aluminum Drain Plugs,High Performance Multi-Louvered Fins, Innovative 'B-Tube' Technology.
