Information
Intake manifold gasket
The Genuine Porsche 90111019100 intake manifold gasket is an OE paper gasket for selected Porsche 911E and 911S 1969–1971 intake systems. It helps seal the intake manifold, prevent vacuum leaks and maintain correct engine running. Ideal for MFI intake service, engine rebuilds, gasket replacement or classic Porsche restoration using Genuine Porsche parts.
Sold individually, 6 required per vehicle
Fits:
Porsche 911 E/S 1969 - 1971
Diagram ref no 27
This gasket is used on selected classic Porsche 911E and 911S intake systems.
What This Part Does / Functions
• Seals the intake manifold mating surface
• Helps prevent unwanted air / vacuum leaks
• Supports correct fuel and air mixture control
• Helps maintain smooth idle and throttle response
• Provides correct OE Porsche gasket profile and fitment
• Replaces a compressed, torn, hardened or leaking original gasket
• Supports correct reassembly after intake manifold removal
• Helps maintain factory intake system sealing on classic 911E/S models.
Why Replace This Part?
Intake manifold gaskets are exposed to heat, fuel vapour, pressure changes and age-related hardening. Over time, the gasket can compress, tear, become brittle or lose its ability to seal correctly. A leaking intake gasket can allow unmetered air into the engine, causing poor idle quality, hesitation, lean running or difficult tuning. Replacing it with a Genuine Porsche OE intake manifold gasket helps restore proper intake sealing and supports reliable running on the 911E/S mechanical fuel injection system.
Common Symptoms of a Failed Intake Manifold Gasket
• Rough or unstable idle
• Intake air / vacuum leak
• Lean running condition
• Hesitation or poor throttle response
• Difficult mixture adjustment or tuning
• Engine hunting at idle
• Misfire-like running symptoms
• Visible gasket damage after intake removal.
When to Replace This Part
• Whenever the intake manifold is removed
• During MFI intake system service or restoration
• If an air leak is found at the intake manifold joint
• If the original gasket is torn, crushed or brittle
• During engine rebuild or top-end work
• When diagnosing poor idle or lean running issues
• When restoring the intake system with Genuine Porsche parts
• Whenever Porsche workshop procedure recommends gasket replacement after disassembly.
Where It Fits on the Car
This gasket fits at the intake manifold sealing face on the engine intake system. It sits between the intake manifold and its mating surface, creating an air-tight seal once the manifold is correctly installed and torqued. Correct surface preparation and careful installation are important to prevent air leaks.
