CSF E46 M3 Triple-Pass Radiator
Description
CSF quality and performance is unrivaled with an easy direct-fit install.  This E46 M3 radiator is a factory replacement using all factory shrouding, clip-on hoses, and mounting points.

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 a three-pass flow design for maximum cooling in race environments and extreme driving conditions - an E46 M3 industry first.  
 
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.  CSF's Racing & High Performance Division is able to produce a premium high performance cooling system with a level of quality and craftsmanship that is usually found in products with a much higher price point due to their economies of scale of over 600,000 units sold globally every year.
 
All CSF radiators come with a two year warranty against defects in craftsmanship.
