Air duct engine
These OE Match engine air ducts are replacement engine cooling air duct components for Porsche 356A, 356B, and 356C models. They are available for left and right side positions and are designed to match the original-style fitment and function within the engine cooling system.
Left and Right Sides – Sold Separately
Fits:
Porsche 356A 1955 - 1959
Porsche 356B 1959 - 1963
Porsche 356C 1963 - 1965
Section of diagram ref no 30
The engine air duct helps direct cooling air through the engine compartment and over the correct engine areas. Properly fitted air ducts are important for maintaining efficient air-cooled engine temperature control and supporting reliable engine operation.
Functions
• Replaces the engine air duct
• Helps direct cooling air through the engine bay
• Supports correct air-cooled engine temperature control
• Helps maintain factory-style cooling airflow
• Replaces missing, cracked, corroded, dented, or damaged original ducts
• Suitable for engine rebuilds, cooling system work, and restoration
• OE Match replacement for classic Porsche engine cooling repair
Why Replace This Part?
Engine air ducts can become damaged, dented, corroded, cracked, loose, or missing due to age, heat, vibration, previous engine repairs, or restoration work. A damaged or missing air duct can reduce cooling efficiency, disrupt airflow, and leave the engine bay incomplete. Replacing the duct helps restore correct airflow and original-style engine compartment detail.
When to Replace This Part
• The original air duct is missing, cracked, corroded, or damaged
• Cooling air ducting is incomplete or incorrectly fitted
• Engine cooling performance is being inspected
• The engine has been removed, rebuilt, or restored
• Engine bay tinware or ducting is being replaced
• Incorrect or mismatched ducting has been fitted
• The vehicle is undergoing Porsche 356 engine bay restoration.
Where it fits on the car
These air ducts fit within the engine cooling air ducting system on Porsche 356A, 356B, and 356C models. One duct is used for one side of the engine bay, and the other is used for the opposite side, depending on the part selected.
