What This Product Does:
- The oil cooler air duct is part of the engine’s oil-cooling / heat-exchange system. It channels ambient air into the oil-cooler core or directs heated air away from the cooler to help maintain optimum oil temperature.
- In the 944 S2 the engine is front-mounted and uses an oil cooler (in addition to the radiator) to help manage oil temperature. The duct ensures that sufficient fresh air flows through/around the oil cooler fins, and that hot air is removed efficiently.
- Proper operation of the duct helps the oil-cooler perform its job, thereby helping to keep engine oil at safe operating temperatures, protecting bearings, seals and prolonging engine life.
Symptoms & Signs of Wear / When To Replace:
- Visible damage, cracks or missing ducting around the oil cooler – if the duct is cracked, split or detached, air-flow may be reduced.
- Over-temperature of engine oil or higher than normal oil temps (especially under load or warm ambient conditions) — could indicate the oil cooler is not getting enough air due to duct failure.
- Reduced or blocked airflow in the front ventilation channel around the oil cooler (debris, lost mounting, broken duct).
- Increased oil cooler noise or rattles – if the duct is loose or broken, air turbulence or vibration may be noticeable.
- Signs of heat damage downstream of the cooler – e.g., heat-scorching, melted components, because hot air was not guided away properly.
- Ensures oil-cooler efficiency: Without the duct functioning correctly, the oil cooler may not receive enough fresh airflow or may overheat, which can degrade oil quality and accelerate wear.
- Protects engine reliability: Proper oil temperature helps protect engine bearings, seals and performance integrity — the duct contributes indirectly but significantly.
