The new oil cooler for the Porsche 914-6 is based on the incredibly popular and successful CSF 911/930 Turbo Engine Oil Cooler (CSF #8242). 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.

The high-performance core uses 7 cooling tubes with 8 rows of fins. Between the ultra efficient fin design and high flow tubes, the CSF cooler is ~10% more efficient than a brand new OE unit and up to 25% more efficient than a used unit.

Because the base plate of the cooler is also a common problem area, CSF sought to improve this area as much as possible. Instead of the original cast design, the CSF cooler uses a CNC machined billet aluminum plate. This offers a perfectly flat mounting surface which is both stronger and more resistant to warping over time. You’ll also notice a special helix design which adds strength while keeping weight at a minimum.

Each unit is Individually Leak and Pressure Tested with a 10 year warranty
New OEM coolers from Porsche are extremely scarce/hard to source and cost $1,300+
