Direct replacement for the factory DCT cooler and fits with no modification - but has a dual-pass layout for longer exposure to cooling air. The better cooling performance reduces the potential for temperature-related faults and limp mode encountered during track events. Instead of a single pass through the cooling tubes, the fluid goes through another set of tubes. Instead of increasing surface area by making a larger core the dual-pass does the same within the original dimensions.
  • Made with CSF’s AC condenser technology using a 1-row super-high pressure 26mm multi-channel microtube.
  • Dual-pass high performance core with 12 cooling tubes vs. OEM single-pass with 6 tube design.
  • Lab tested at approximately 30% more efficient than the OEM cooler.
  • High-density multi-louvered fin design.
  • Drop-in fit requiring no modifications to install. Accepts all attaching OEM components including oil-line connections, mounting brackets, and shroud/ducting.
  • World’s 1st and only true plug-and-play upgraded DCT transmission cooler for F8X

  • Replaces BMW part numbers 17112284503 and 17212284241.

    Racing Homologation Note: This piece is a direct replacement for the factory BMW part, however, it has not been homologated as a replacement for your original. If your factory race car is still competing under homologation rules (FIA, SRO, etc) you must get approval from your sanctioning body to use anything but the original, homologated part.

    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.
