The M5 / M6 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 so ensure all of your connections and fitment follows the factory mounting. 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.
