# CSF BMW E28 M5 (US and Euro) / E24 M635CSi / E24 M6 High-Performance Radiator

CSF teamed up with A/C Solutions to develop this new radiator. Their founder, Austin Caccavo, is a long time E28 enthusiast. He started the company after updating the A/C system on his own E28. The relationship began with CSF manufacturing A/C condensers for their upgrade and conversion kits which eventually led to Austin asking if CSF would make a High-Performance radiator for the E28 M5. Austin and his team worked closely with CSF's engineering team to develop this radiator for perfect fitment, optimal performance, and all the features E28/E24 owners could hope for.
