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+

Engine Oil Coolers, Radiators & Heat Exchangers – Precision Cooling for Porsche Performance
The engine oil cooler and heat exchanger system plays a critical role in managing temperature within your Porsche’s engine. By transferring excess heat away from the oil and other fluids, these components ensure stable operating temperatures, consistent lubrication, and maximum engine longevity — especially under demanding performance conditions.
At Design911, we offer a full range of engine oil coolers, radiators, and heat exchangers for Porsche models old and new. Built from high-efficiency aluminium or reinforced composite materials, these components are designed to deliver superior cooling performance, durability, and perfect fitment — ensuring your Porsche performs at its best, on road or track.
Whether replacing a worn-out unit or upgrading for improved thermal efficiency, our oil cooling components provide reliable temperature control and enhanced performance.
What Do Engine Oil Coolers, Radiators & Heat Exchangers Do?
These components regulate oil and engine temperatures to maintain optimal performance and prevent overheating.
Core Functions:
- Dissipate
excess heat from the engine oil, coolant, or transmission fluid.
- Maintain
consistent oil viscosity and prevent breakdown under load.
- Protect
internal engine components from heat-related wear and failure.
- Improve overall performance efficiency during extended drives or track sessions.
Together, the oil cooler, radiator, and heat exchanger form an essential thermal management system, helping your Porsche run at peak performance while protecting vital components.
Why Do Oil Coolers & Heat Exchangers Fail?
Over time, exposure to heat cycles, vibration, and contaminants can lead to efficiency loss or complete failure.
Common Causes of Failure Include:
- Corrosion
or cracking from age or road debris impact.
- Internal
clogging caused by sludge or contaminated oil.
- Leaking
seals or fittings, reducing pressure and fluid efficiency.
- Thermal
fatigue, leading to reduced cooling capacity.
- Poor maintenance or coolant neglect, accelerating deterioration.
Symptoms of failure can include high oil temperatures, oil leaks, coolant contamination, or reduced engine performance, all of which signal the need for inspection or replacement.
Why Replace Oil Cooling Components?
Replacing a worn or leaking oil cooler, radiator, or heat exchanger is essential to preserve lubrication quality and prevent costly overheating damage. Our precision-fit, high-durability components restore proper cooling balance and reliability under all conditions.
Key Benefits:
- Restores efficient oil and fluid temperature regulation.
- Prevents overheating and engine wear.
- Improves reliability under heavy load or track use.
- Constructed from corrosion-resistant, high-performance materials.
- Direct-fit compatibility for classic and modern Porsche engines.
- Ideal for rebuilds, maintenance, and performance upgrades.
Upgrading or replacing your cooling system components helps ensure your Porsche’s engine stays efficient, durable, and ready for spirited driving.
Highlights:
- Comprehensive range of Porsche oil coolers, radiators, and heat exchangers.
- Precision-engineered for consistent temperature control.
- Constructed from lightweight, corrosion-resistant materials.
- Designed for reliability in both road and motorsport conditions.
- Improves lubrication and protects engine performance.
- Perfect for maintenance, rebuilds, or performance enhancements.
