This replacement pipe provides a dedicated oil flow path within the gearbox cooling circuit, allowing transmission oil to reach the cooling system where excess heat can be managed.
An economical aftermarket alternative to the original Porsche component, it is ideal for replacing a leaking, corroded or damaged supply pipe.
For PDK transmission applications only. Not suitable for manual gearbox installations.
What Does It Do?
The oil cooler supply pipe transports transmission oil from the PDK gearbox towards the cooling circuit.
As the gearbox operates, friction and internal mechanical activity produce heat. The transmission cooling system helps remove excess heat by passing oil through a heat exchanger.
The supply pipe forms the feed side of this system, delivering oil for cooling before it continues through the return circuit.
Why Is It Important?
A dependable oil supply is essential for keeping the PDK transmission within its intended operating temperature range.
A faulty supply pipe may cause:
- Transmission oil escaping from damaged pipework
- Reduced oil volume within the cooling system
- Oil staining beneath the vehicle
- Insufficient oil circulation through the heat exchanger
- Increased risk of gearbox overheating or damage
Maintaining the condition of the supply pipe helps preserve the performance and reliability of the transmission cooling circuit.
Why Do Oil Cooler Supply Pipes Fail?
The pipe is exposed to changing temperatures, vibration and environmental conditions throughout its service life.
Deterioration can occur through:
- Corrosion from road moisture and salt
- Fatigue caused by repeated heating and cooling
- Damage to pipe connections or sealing surfaces
- Contact with surrounding mechanical components
- Accidental damage during transmission repairs
When Should It Be Replaced?
Renew the supply pipe if inspection reveals corrosion, cracks, deformation or oil seepage around its connections.
Replacement may also be necessary when carrying out repairs to the PDK gearbox cooling system, particularly if the original pipe cannot be safely reused.
Investigate any unexplained gearbox oil loss immediately to avoid possible transmission damage.
Installation Notes
Before installation, examine the heat exchanger connections, sealing rings and pipe retaining hardware.
Ensure the replacement supply pipe follows the correct routing and is securely fitted without twisting or placing stress on the connections.
Use the correct transmission oil and follow Porsche's specified PDK filling, temperature checking and oil level procedures. Inspect for leaks after installation.
Key Features
- OE Match aftermarket replacement supply pipe
- For applicable Porsche 987.2, 981 and 718 PDK transmissions
- Delivers transmission oil to the gearbox cooling circuit
- Helps maintain correct oil flow through the heat exchanger
- Replaces damaged, corroded or leaking supply lines

Designed for Porsche Boxster and Cayman models equipped with the PDK dual-clutch gearbox, this pipe forms part of the transmission oil cooling system, providing a return passage for oil circulating through the gearbox heat exchanger.
It is a practical replacement for an original pipe that has developed corrosion, damage or leakage.
What Does It Do?
The oil cooler return pipe carries transmission oil through the return side of the PDK gearbox cooling circuit.
During operation, the PDK transmission generates heat through its internal gears and clutch assemblies. The oil cooling system helps manage this heat by circulating transmission oil through a heat exchanger.
The return pipe completes part of this circulation route, allowing oil to flow back through the transmission cooling system.
Why Is It Important?
The PDK gearbox relies on correctly circulating transmission oil to maintain suitable operating temperatures and lubrication.
A damaged or leaking return pipe can result in:
- Loss of transmission oil
- Oil residue around gearbox cooling connections
- Reduced efficiency of the oil cooling circuit
- Potential gearbox overheating
- Transmission warning messages if operating conditions become abnormal
Maintaining leak-free oil pipes helps protect the gearbox and supports dependable transmission operation.
Why Do Oil Cooler Return Pipes Fail?
Over time, the original pipe may deteriorate due to exposure to road salt, moisture, temperature changes and vibration.
Common causes of failure include:
- Corrosion affecting exposed pipe sections
- Damaged or deteriorated connection seals
- Physical damage during gearbox maintenance
- Fatigue around pipe bends or mounting points
- Incorrectly secured or strained connections
When Should It Be Replaced?
Replacement is recommended when the return pipe shows visible corrosion, cracking, deformation or signs of transmission oil leakage.
It should also be inspected when investigating gearbox oil loss or servicing the PDK heat exchanger and associated cooling lines.
Any suspected transmission oil leak should be investigated promptly to prevent potential gearbox damage.
Installation Notes
Inspect the pipe mounting points, connection fittings and seals before installation.
Replace damaged sealing components as required and ensure the pipe is routed correctly without unnecessary strain. Use the manufacturer's specified tightening procedures.
Following installation, check the transmission oil level using the correct Porsche PDK service procedure and inspect all connections for leaks.
