What This Product Does
The cooler transfers heat away from the engine lubricant to help manage its temperature. The gasket seals the cooler's mounting joint. Supplying these components together allows the cooler and its associated sealing interface to be renewed during the same repair.
Functions
- Removes excess heat from engine oil.
- Helps maintain the lubricant's operating temperature.
- Seals the joint between the cooler and its mounting assembly.
Technical Details
- Oil cooler reference: 95810727101.
- Pierburg cooler reference: 7.09269.58.0.
- Oil cooler gasket reference: 95810717501.
- Cayenne diagram application: 92A (958), 3.0L Hybrid, 2011–18; model/engine identifiers 06EC, CGEA, CGE, CGFA and CJT.
- Panamera diagram application: 970 (G1), 3.0L Hybrid, 2012–16; model/engine identifiers CGEA, CGE and CGFA.
- The supplied kit description identifies an engine oil cooler and gasket; additional fixings, seals and fluids are not specified.
Symptoms of Fault
- Fresh oil traces or dampness around the cooler joint.
- Engine oil temperatures that remain unusually high.
- Unexplained fluid loss or inconsistent operating temperatures.
- Oil contamination in the coolant, or coolant contamination in the oil, where an internal exchanger leak is present.
These signs can have other causes. Inspect the cooler, its seals and neighbouring connections before deciding which components require replacement.
Why Replacement Matters
A leaking gasket or damaged cooler can compromise sealing or oil temperature management. Renewing a confirmed faulty cooler together with its gasket addresses both the component and its mounting seal. If fluids have become contaminated, repairing the source remains necessary; flushing alone does not correct the fault.
FAQs
Does a high oil temperature prove the cooler has failed?
No. Oil level, temperature regulation and other cooling-system faults should also be investigated.
Are all installation consumables included?
Only the cooler and gasket are identified. Compare the kit contents with the relevant parts diagram and repair procedure for any additional requirements.
What should happen if oil and coolant appear to be mixing?
Stop driving and arrange diagnosis. The source needs confirmation before replacement, followed by appropriate cleaning of affected circuits.

Genuine Porsche speed nut for the engine lubrication oil cooler assembly.
Fits
- Porsche 911 3.2L 1984–1986
- Porsche 911 3.2L G50 1987–1989
Check fitment for your specific vehicle (model, year, engine) before ordering.
Diagram: 104-05, item 54 (1984–86); Diagram: 104-05, item 51 (1987–89).
What This Product Does
The speed nut forms part of the engine oil cooler installation. It provides a retained fastening point for the associated cooler assembly hardware, helping the relevant component remain correctly secured when the specified screw or fixing is installed.
Functions
- Provides a fastening point within the engine oil cooler assembly
- Retains the corresponding fixing after installation
- Replaces a missing, damaged or weakened original speed nut
Technical Details
- Genuine Porsche component
- Porsche part number: 99950722902
- Part type: speed nut
- Assembly: engine lubrication oil cooler
- Diagram quantity: four per applicable assembly
Symptoms of Fault
- Original speed nut is missing during disassembly
- Fastener no longer grips securely
- Nut is distorted, corroded or damaged
- Associated oil cooler hardware cannot be tightened correctly
- Movement or looseness is present at the relevant mounting point
Why Replacement Matters
A damaged or missing speed nut can prevent the associated fixing from being secured as intended. Replacing it with the correct Porsche part helps preserve the original fastening arrangement and avoids reusing hardware that has lost its grip or become distorted. Inspect the adjoining screws, brackets and mounting points while the assembly is accessible.
Support & Advice
Confirm part number 99950722902 against the vehicle details and the removed component before ordering. Items selected through a part-number search cannot be returned when ordered incorrectly.

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.
