NEW CSF Porsche 914-6 Engine Oil Cooler
Classic Style with Modern Technology
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.
While the original design was effective at the time, they have not aged well. In addition, 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.
Design and Engineering
The original Behr Cooler was designed back in the 1960s and definitely shows its age at this point. Original coolers can be ultrasonically cleaned and refurbished but there is good chance they will start leaking after cleaning. The cleaning process may cause the coolers to fail due to its old and brittle materials, or it can remove corrosion and debris that has kept the original from showing the leak beforehand. However, the core is not the only source of leaks. The OEM cast base plate that mounts to the block can become slightly warped or aging porosity can cause the seals to not seat correctly and leak.
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” Catalog 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.
For development of the 914-6 Engine Oil Cooler, CSF teamed up with the leading Porsche engine building experts at SV Auto. Their deep knowledge of classic Porsche engines and expertise in restoration gave CSF invaluable insight into how to best approach the design and construction. Long time R&D Partner and CSF Dealer Brian Day at Euro Parts West was also a critical partner in the development of the oil cooler design.
Attention To Detail
CSF’s goal for the 914-6 Oil Cooler was to recreate the original cooler with a modern interpretation of the design while improving functionality and reliability. To accomplish this, CSF spent countless hours in research and development. Brain Day was instrumental in really helping CSF engineers understand the 914-6’s oil cooling system. These details and deep understanding allowed for proper engineering and creating a cooler that could fit such a wide variety of models.
