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

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.

What This Product Does
This radiator forms part of the engine oil cooling circuit. Heat passes out through the cooler, helping control the temperature of the oil used to lubricate internal engine components. The cooler works alongside the oil lines, thermostat and associated cooling hardware.
Functions
- Transfers excess heat away from engine oil.
- Supports oil temperature management during operation.
- Helps maintain suitable conditions for engine lubrication.
Technical Details
- Component: engine oil cooler.
- Installation position: inside the front wing.
- Brand: OE Match.
- Part identified in both supplied assembly diagrams: 96420722004.
Symptoms of Fault
- Oil drips or dampness around the cooler and connecting lines.
- Oily deposits across the cooling fins.
- Oil temperature remaining unusually high during sustained use.
- Damaged or obstructed fins restricting airflow.
- Visible corrosion or impact damage to the cooler.
Why Replacement Matters
A leaking or damaged cooler can compromise oil temperature control and allow oil loss. Renewing a confirmed faulty unit addresses the damaged component, but adjoining pipes, unions, seals and mountings should also be inspected. Establish whether leakage originates from the cooler itself or a nearby connection before replacement.
FAQs
Does high oil temperature prove the cooler has failed?
No. Oil level, thermostat operation and airflow can also affect temperature, so diagnosis should cover the wider system.
What should be inspected during replacement?
Check the connected oil lines, sealing points, mounting rubbers and surrounding airflow path for deterioration or damage.
How can a suspected leak be confirmed?
Inspect the cooler and its connections to locate the source; appropriate pressure testing can help confirm leakage.
