Information
Intake manifold rubber sleeve
This OE Match intake manifold rubber sleeve is a replacement rubber connecting sleeve for Porsche 911 and 914 models. It is designed to match the original-style fitment and function, helping provide a secure air intake connection within the engine induction system.
Fits:
Porsche 911 1965 - 1973
Porsche 914/6 1970 - 1972
Diagram ref no 6/1
The intake manifold rubber sleeve helps connect and seal sections of the intake manifold or induction system. A good sleeve helps maintain correct airflow, prevents unwanted air leaks, and supports smooth engine running, correct mixture control, and reliable intake system performance.
Functions
• Replaces the intake manifold rubber sleeve
• Helps seal the intake manifold connection
• Supports correct airflow through the induction system
• Helps prevent vacuum leaks and unmetered air entry
• Supports smooth idle and consistent engine performance
• Replaces cracked, hardened, split, loose, or perished original sleeves
• OE Match replacement for classic Porsche intake system repair.
Why Replace This Part?
Rubber intake sleeves are exposed to heat, fuel vapour, oil mist, vibration, and age-related deterioration. Over time, the rubber can harden, crack, split, shrink, or lose its sealing ability. A failing sleeve may cause vacuum leaks, rough idle, poor running, hesitation, difficult starting, or incorrect fuel mixture. Replacing the sleeve helps restore a secure intake seal and dependable engine performance.
When to Replace This Part
• The rubber sleeve is cracked, split, hard, loose, or perished
• Vacuum leaks are suspected around the intake manifold
• The engine has rough idle, hesitation, or poor running
• Intake manifold parts have been removed or serviced
• Fuel injection or carburettor components are being inspected
• The intake system is being rebuilt or restored
• Preventative replacement is being carried out during engine service.
Where it fits on the car
This sleeve fits within the engine intake manifold / induction system on Porsche 911 and 914 models. It is used at the intake connection point where a rubber sleeve seal is specified.
