The intake manifold gasket seals the joint between the manifold and cylinder head to prevent unwanted air leaks. A good seal is essential for correct fuel mixture, stable idle, smooth throttle response, and reliable engine performance.

Functions
• Replaces the intake manifold gasket
•  Seals the intake manifold to the cylinder head
•  Helps prevent vacuum and intake air leaks
•  Supports correct fuel mixture and combustion
•  Helps maintain smooth idle and throttle response
•  Used during intake manifold, fuel injection, or engine service
•  OE Match replacement for Porsche 911E and 911S intake repair.

Why Replace This Part?
Intake manifold gaskets can become brittle, compressed, cracked, or damaged due to age, heat cycles, fuel vapour, and previous manifold removal. A failed gasket can allow unmetered air into the intake system, causing poor idle, hesitation, lean running, misfires, reduced performance, or difficult tuning. Replacing the gasket helps restore proper intake sealing and engine running quality.

When to Replace This Part
•  The intake manifold has been removed
•  Vacuum leaks or intake air leaks are suspected
•  Idle is rough, unstable, or difficult to adjust
•  Engine hesitation, lean running, or misfires are present
•  Fuel injection or intake system work is being carried out
•  The original gasket is brittle, cracked, compressed, or damaged
•  The vehicle is undergoing Porsche 911E or 911S engine restoration.

Where it fits on the car
This gasket fits between the intake manifold and cylinder head on Porsche 911E and 911S models from 1969 to 1971. One gasket is used per intake port where specified.
