Designed for classic air-cooled engines, this duct plays a crucial role in managing airflow within the engine bay. It ensures that sufficient cooling air reaches the oil cooler, which is essential for maintaining proper oil temperature and overall engine health.
Fits:
Porsche 911 - 1972 to 1989
Porsche 914-6 - 1970 to 1976

The air duct channels cooling air directly to the oil cooler, ensuring efficient heat dissipation from engine oil. This helps maintain stable oil temperatures and prevents overheating in air-cooled engines. Proper airflow management is critical for consistent engine performance and longevity.
Function
• Directs cooling air to the oil cooler
• Improves heat dissipation from engine oil
• Supports stable engine operating temperatures
• Ensures efficient airflow within engine tinware system
Over time, air ducts can crack, warp, or go missing during engine work. A damaged or missing duct reduces airflow to the oil cooler, leading to higher oil temperatures and potential engine wear. Replacing this component ensures proper cooling airflow, protects engine components, and maintains optimal performance - especially important for air-cooled engines.
When to replace:
• Cracked, broken, or missing duct
• Overheating or high oil temperatures
• During engine rebuild or restoration
• Poor airflow or incorrect engine tinware setup
• Preventative maintenance on classic vehicles
