Information
Radiator oil cooler on engine.
This engine oil cooler is a direct replacement for the original Porsche unit. It functions as a water-to-oil heat exchanger, efficiently transferring heat from the engine oil to the coolant to maintain optimal operating temperature. Built to OEM specifications, it ensures reliable cooling, consistent oil viscosity, and long-term engine protection under demanding conditions.
Fits:
Porsche 986 Boxster 2.5L / 2.7L 1994 - 2004
Porsche 987 Boxster 2.7L / 3.2L 2005 - 2008
Porsche 987C Cayman S 3.4L 2005 - 2008
Diagram Ref No 18.
Benefits:
• Maintains optimal oil temperature to reduce wear, prevent oil breakdown and engine damage
• Direct-fit replacement ensures correct mounting, connections and flow rate
• Engineered for long life and reliability even in high-stress driving environments
Over time, engine oil coolers are exposed to high thermal cycles, pressure, and contaminants that can cause internal clogging, corrosion, or coolant-to-oil leaks. A failing cooler can lead to elevated oil temperatures, reduced lubrication, and even engine damage due to oil breakdown or cross-contamination.
When to replace:
• When oil temperature readings are abnormally high or fluctuating.
• If you notice oil in the coolant or coolant in the oil (a sign of internal leakage).
• During engine rebuilds or cooling system overhauls to ensure proper performance.
• As preventive maintenance on older engines or vehicles used in track or high-load conditions.
Replacing the oil cooler restores efficient heat transfer, maintains stable operating temperatures, and ensures long-term engine reliability.

The OE Match Front Oil Cooler Oil Pipe is a high-quality replacement lubrication system component designed to transfer engine oil between the oil cooling system and the engine on compatible Porsche models. Manufactured to OE specifications for fit, flow capacity and durability, this oil pipe ensures efficient oil circulation while maintaining the correct operating temperature of the engine.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
Diagram Ref No 16
Constructed from high-quality corrosion-resistant metal tubing with precision-formed bends and OE-style threaded connections, the oil pipe is engineered to withstand high oil pressures, elevated temperatures and continuous engine vibration. Designed to provide a secure, leak-free connection, it plays a vital role in the performance and longevity of Porsche's engine lubrication and oil cooling system.
What This Product Does:
- Transfers engine oil to and from the front oil cooler.
- Maintains efficient oil circulation throughout the lubrication system.
- Supports effective engine oil cooling.
- Helps regulate engine operating temperature.
- Delivers a consistent supply of lubricating oil under pressure.
- Provides secure, leak-free oil transfer between components.
- Helps protect internal engine components from excessive wear.
- Forms an essential part of the engine's oil cooling and lubrication system.
Symptoms Of Wear Or Failure:
- Visible engine oil leaks.
- Oil residue around the oil pipe or fittings.
- Low engine oil level.
- Oil pressure warning light.
- Oil smell from the engine bay or underneath the vehicle.
- Corrosion or rust on the oil pipe.
- Cracked or damaged pipe connections.
- Increased engine operating temperatures.
- Reduced oil circulation.
- Premature engine wear caused by lubrication loss.
Why Replacement Matters:
- The front oil cooler oil pipe is continuously exposed to hot engine oil, high operating pressures, vibration, road debris and environmental corrosion. Over time, the pipe can deteriorate through corrosion, impact damage or fatigue, while threaded connections and sealing surfaces may begin to leak.
- A leaking or restricted oil pipe can reduce oil pressure and compromise the engine's lubrication and cooling efficiency. Continued operation with insufficient oil flow can accelerate wear of bearings, camshafts and other critical engine components, potentially leading to severe engine damage and costly repairs.
- Replacing a worn or damaged front oil cooler oil pipe restores reliable oil circulation and ensures the engine's lubrication and cooling systems continue to operate efficiently. The OE Match replacement provides factory-style fitment, robust construction and dependable long-term sealing performance, helping maintain the reliability, performance and longevity expected from your Porsche.

Its direct OE-style fitment ensures straightforward installation and reliable, leak-free operation, making it ideal for both routine maintenance and engine restoration projects.
What This Product Does:
- Dissipates heat from the engine oil.
- Maintains optimum engine oil operating temperature.
- Helps preserve correct oil viscosity.
- Protects internal engine components from excessive heat.
- Supports efficient engine lubrication.
- Improves engine reliability during normal and high-performance driving.
- Provides secure oil connections via the integrated screw socket.
- Forms an essential part of the engine lubrication and cooling system.
Symptoms Of Wear Or Failure:
- Engine oil leaks around the cooler or connections.
- Visible corrosion or physical damage to the cooler.
- Elevated engine oil temperatures.
- Engine overheating under load.
