  • High performance aluminum core
  • CSF B-Tube design
  • Designed and tested in the USA
This radiator for M Sport models includes connections for the factory engine and transmission oil coolers.

The OE-Plus CSF radiators for the offer much of the same technology and benefits as their Aluminum and Triple-Pass designs, but at a more accessible price. OE-Plus are the same dimensions as the stock radiator but with better materials and greater surface area on the vanes for improved cooling (as much as 15% better than original). CSF uses a proprietary "B-Tube" design for their vanes. Instead of a single oval radiator tube, CSF has two tubes in the shape of a "B" that have more surface area and greater strength. In addition, CSF can use a thinner and lighter material that is more efficient.

OE-Plus radiators have plastic end tanks and an aluminum core for a drop-in fitment, just like the OEM design. 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. 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.

This more-efficient radiator replaces Original BMW part numbers 17118672103 and 17117606017.

Fitment note: F30 3-series and F32 4-series models must be equipped with the optional M Sport package.
