The new oil cooler for the Porsche 914-6 is based on the incredibly popular and successful CSF 911/930 Turbo Engine Oil Cooler. Both of these oil coolers went through 2+ years of development and multiple rounds of prototypes. The CSF Porsche 914-6 Engine Oil Cooler’s world debut at Rennsport Reunion 2023 was met with incredible support and enthusiasm from the community. Obviously air-cooled enthusiasts know the struggles associated with the oil cooler located on the engine block of the old flat six motor. With the 914-6 swaps/conversions becoming ever more popular, this new Oil Cooler will be a game changer for classic Porsche owners and restoration shops.


Designed and built off the OEM Behr cooler, the CSF system improves the original design for peak performance and cooling on your air-cooled Porsche.
