This OE Match intake manifold gasket set includes 6 replacement sealing gaskets used between the intake manifolds and cylinder heads. The set is designed to match the original-style fitment and function, helping restore a secure seal within the engine intake system.

The intake manifold gaskets seal the joint between the manifolds and cylinder heads 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 all 6 intake manifold gaskets
•  Seals the intake manifolds to the cylinder heads
•  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. Failed gaskets can allow unmetered air into the intake system, causing poor idle, hesitation, lean running, misfires, reduced performance, or difficult tuning. Replacing all 6 gaskets together helps restore balanced intake sealing across the engine.

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 set fits between the intake manifolds and cylinder heads on Porsche 911E and 911S models from 1969 to 1971. One gasket is used per intake port.
