A leader in European engine cooling, CSF Ultimate Performance Cooling strives to build and engineer the most advanced, efficient, and reliable cooling systems in the world. CSF quality and performance provides proper cooling with an easy direct-fit install. This E46 radiator is a factory replacement using all factory shrouding, clip-on hoses, and mounting points.
CSF manufacturers a wide variety of sophisticated cooling systems with more than 117 different applications ranging from high performance all-aluminum direct-fit replacement radiatior to complete custome applications for race cars, power sports, off-road, marine and industrial uses.
“Drop-in fit” requiring no modifications to install. Accepts all attaching OEM components including “quick-connect” hoses, AC condenser, mounting brackets, and fan shroud
CNC machined “quick-connect” inlet/outlet connections
CNC machined brackets and fittings for superb fit and durability
All-aluminum race style drain plug
1 hour “mirror finish” hand polish
For E46 3 Series,
CSF's "B-tube" radiator tubes are specially engineered in the shape of a flat B,
resulting in a tube that is stronger than the normal "O" shaped tube. CSF is able to use thinner and lighter aluminum with better cooling efficiency because of the shape of the radiator tubes.and a precision multi-louvered fin to increase heat rejection performance and surface area contact.
Additionally, this CSF part has 20% 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. 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.
Every CSF quality radiator goes through a testing process in our state-of-the-art testing lab. Our procedures and requirements set the bar for cooling system reliability and performance:
CSF ensures that every radiator is individually wrapped and packaged with extra protection for safe delivery to you.
