This comprehensive service kit centers around the OE Match engine oil cooler (OE ref part no. 99610702559) - a direct-fit cooling radiator that exchanges heat between engine oil and the coolant circuit to keep oil temperatures within proper limits under all driving conditions. In addition to the cooler itself, the kit includes authentic Porsche OEM parts necessary for a proper installation and leak-free operation.

Kit Includes:
•  OE Match Engine Oil Cooler - OE ref no 99610702559
•  Porsche Genuine hose - 99610623053
•  Porsche Genuine Seals - 99970754740 and 99970738940
•  Porsche Genuine hex screw - N10546403
•  Porsche Genuine hose clamps  - 99951255400 and 99951265209

These genuine parts are matched with the OE Match cooler to ensure factory-level sealing and durability, removing the guesswork from sourcing the correct components for an engine oil cooler service.

The engine oil cooler and its associated seals and hardware are subject to thermal cycling, pressure variation, and long-term exposure to heat and chemicals. Over time, coolers can become corroded, clogged, or internally separated, and seals can dry out, harden, or fail. This leads to:
•  Oil leaks
•  Elevated oil temperatures
•  Reduced lubrication efficiency
•  Possible engine damage from overheating or loss of oil pressure

Replacing the entire oil cooler and related seals at the same time delivers a comprehensive refresh of the system - reducing the risk of repeat leaks, improving cooling efficiency, and helping prolong engine life.

When to replace. Install this oil cooler service kit when:
•  You detect oil or coolant leaks near the oil cooler
•  The vehicle has high mileage with original components
•  You’re experiencing oil temperature fluctuations or overheating conditions
•  You are performing a coolant system or engine refurbishment
•  Internal oil cooler passages show blockage or contamination
