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.

OE Match engine oil cooler / radiator designed to replace the original Porsche oil cooler that sits on the engine’s cooling circuit. It acts as a crucial element of the engine oil cooling system, transferring heat from the engine oil to the coolant or ambient airflow (depending on the specific engine layout) to maintain optimal oil temperature during operation.
Fits:
Porsche 996 1998 - 2005
Porsche 997.1 3.6L 2005 - 2008
Porsche 986 Boxster S 3.2L 1999 - 2004

The oil cooler regulates the temperature of engine oil as it circulates through the engine. By reducing thermal load on the oil, it helps:
• Maintain correct oil viscosity for effective lubrication
• Reduce wear on internal engine components
• Improve engine performance under load or high-temperature operation
• Prevent oil breakdown and reduce risk of overheating.
Without an effective oil cooler, engine oil can run too hot, degrading lubrication and potentially accelerating engine wear or promoting heat-related performance issues.
Function
• Heat dissipation: Transfers heat from the oil to coolant or airflow
• Oil temperature stability: Helps keep oil within operational temperature range
• Wear protection: Prevents high temperatures from accelerating oil degradation
• Performance support: Ensures stable lubrication for engine components under stress
The engine oil cooler operates in a harsh thermal environment and can suffer from corrosion, stone impact damage, leaks, or clogging over time. A compromised cooler can lead to:
• Overheated engine oil with reduced lubrication quality
• Increased engine wear and reduced component lifespan
• Poor performance under load and in hot conditions
• Higher risk of oil leaks or contamination
Replacing a worn or damaged oil cooler with a quality OE Match unit helps restore proper oil temperature control, improves overall engine reliability, and supports long-term performance.
When to replace. Replace the oil cooler when:
• There is visible oil leakage from the cooler or its connections
• You observe engine oil temperature issues or overheating warnings
• The cooler shows physical damage such as dents, corrosion, or deterioration
• You are performing a major engine coolant/oil system service

OEMatch Oil Coolers / Radiators / Heat Exchangers — Durability, Sealing, Performance
OEMatch supplies oil coolers, radiators and heat exchangers for Porsche models, addressing thermal management across classic and modern engines. The selection covers core cooling assemblies and related heat-transfer items to help maintain correct oil and coolant temperatures and support long-term engine reliability during everyday use and demanding driving.
Available Types
- Oil coolers (oil-to-air and oil-to-water)
- Radiators and condenser assemblies
- Heat exchangers for oil and transmission cooling
Understanding OEMatch Oil Coolers / Radiators / Heat Exchangers
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original oil coolers, radiators and heat exchangers.
OE (Original Equipment) refers to parts matching original specifications for the oil coolers, radiators and heat exchangers and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM oil coolers, radiators and heat exchangers engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. OEMatch maintains a broad catalogue and continues to develop new lines to support repairs, restorations and routine maintenance for a wide range of Porsche applications.
Benefits Include
- Restores correct oil and coolant temperature regulation to protect internal components
- Reduces risk of overheating and associated engine wear
- Maintains oil viscosity and lubrication under sustained or high-load operation
Why Oil Coolers / Radiators / Heat Exchangers Wear and Fail
- Corrosion or physical damage from road debris and environmental exposure
- Internal clogging from sludge, contaminated oil or coolant residues
- Leaking seals, fittings or thermal fatigue that reduce cooling efficiency
The Importance of Replacing with OEMatch Oil Coolers / Radiators / Heat Exchangers
Replacing a worn or leaking oil cooler, radiator or heat exchanger preserves lubrication quality, prevents overheating and helps avoid costly engine damage. Timely replacement restores thermal balance and reliability for Porsche engines, supporting predictable performance and reducing the risk of secondary failures during road or track use.
Advantages
- Manufactured from corrosion-resistant materials for long service life
- Direct-fit options made to original-spec dimensions for consistent performance
