CSF 2011+ BMW 1 Series M / 07-11 BMW 335i / 2009+ BMW Z4 sDrive30i/Z4 sDrive35i Automatic Transmission Only

CSF provides a high-quality product that exceeds OE standards, gets rid of the plastic end tanks, and improves cooling by 25-30%! Drop-in fitment and more efficient cooling for your street or track car.

  • Drop-in fitment to E82 135i and E90/E92 335i & 335xi automatic transmission models
  • Includes transmission cooler
  • High performance aluminum core
  • Aluminum endtanks instead of plastic
  • CSF B-Tube design
  • Designed and tested in the USA

The E82/E90/E92 CSF Aluminum radiator is designed as a drop-in replacement to the stock system. It uses all of the factory plastic shrouding, hose connections, and mounting points. Although not a fitment concern, the thicker core will tighten tolerances, specifically between the expansion tank and accessory belt. All CSF radiators receive design and development in the USA with additional wind tunnel, vibration, thermal cycle, burst pressure, and salt spray testing done at their production facilities in Southeast Asia. During manufacturing, radiators are individually tested for leaks and receive a 30-point inspection prior to shipping. This part is a much higher level of quality than typical Chinese factory parts. CSF is an OE supplier to several manufacturers as well as providing private-label products for other radiator brands. CSF radiators have a two year warranty.
