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+

Oil Radiators & Heat Exchangers – Optimal Temperature Control for Porsche Performance
Oil radiators and heat exchangers are crucial components in your Porsche’s engine and transmission cooling systems. They regulate oil temperature by transferring heat away from the lubricating or hydraulic fluids, ensuring consistent performance, efficient lubrication, and long-term engine protection — even under extreme driving conditions.
At Design911, we offer a complete range of genuine and manufacturer-quality oil radiators and heat exchangers for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each unit is engineered for precise fitment, efficient heat transfer, and long-lasting reliability — maintaining the high-performance standards that Porsche vehicles are known for.
What Do Oil Radiators & Heat Exchangers Do?
Oil radiators and heat exchangers serve a vital role in
temperature regulation and system protection. They:
- Dissipate
heat from engine or transmission oil to prevent overheating.
- Maintain
stable oil temperature for optimal viscosity and lubrication.
- Extend
component lifespan by preventing thermal damage.
- Support engine and gearbox efficiency under heavy load or high-speed conditions.
By controlling oil temperatures, these parts ensure consistent power delivery, reduced wear, and greater reliability — whether on the road or track.
Why Do Oil Radiators & Heat Exchangers Fail?
Despite being built to handle extreme conditions, these
components can fail over time due to wear, corrosion, or contamination. Common
causes include:
- Corrosion
or internal blockage from debris or degraded fluids.
- Physical
damage from road debris or impact.
- Oil
or coolant leaks due to cracked housings or seals.
- Reduced
heat transfer efficiency from clogged fins or internal scaling.
- Age-related deterioration of internal passages or gaskets.
Symptoms of failure include oil leaks, rising engine temperatures, reduced oil pressure, or contamination between the oil and coolant systems.
Why Replace a Faulty Oil Radiator or Heat Exchanger?
A damaged or inefficient oil radiator can cause overheating, loss of lubrication, and serious engine or transmission damage. Replacing faulty units restores cooling efficiency and ensures your Porsche continues to deliver peak performance and reliability.
Benefits of replacement include:
- Restored oil temperature control and pressure stability.
- Prevention of overheating and oil contamination.
- Improved engine and gearbox longevity.
- Manufacturer-quality construction and fitment for peace of mind.
Each radiator and heat exchanger in this range is designed to meet or exceed factory standards, using advanced materials and precision manufacturing for superior durability, corrosion resistance, and cooling performance.
