After 2+ years of development and 4 rounds of prototypes, the world debut of the CSF Porsche 911/930 Engine Oil Cooler at Rennsport Reunion 2023 was met with resounding enthusiasm. Air-cooled enthusiasts know the struggles associated with the oil cooler located on the engine block of the old flat six motor. CSF’s highly anticipated new release is arguably the most important modern engine upgrade to be released for the 911 in years.
While the original design was effective at the time, they have not aged well. On top of that, there have been no updates to the design and original replacement units can be hard to come by. When the CSF 911 was being built, CSF realized this was a much needed part for the air-cooled community and set out to design something special.

The old original coolers aren’t the only issue though. CSF has gotten many first hand reports of brand new OE coolers from Porsche’s revamped “Porsche Classic” Catalogue leaking within a few months of installation. Apparently the new items available from Porsche are not built as well as the original Behr coolers. CSF has now brought to market a modern OEM+ solution to this vintage design.

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+
