Air Intake Pipe to Throttle Body Gasket 
Sold each - 6 required per car

Restore the integrity of your Porsche's induction system with this OE Match Air Intake Pipe to Throttle Body Gasket. Manufactured for precise fitment and dependable sealing performance, this replacement gasket provides an airtight seal between the air intake pipe and the throttle body, helping to maintain correct airflow and engine efficiency.

Fits:

• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Diagram ref no 23

The induction system relies on sealed connections to ensure that all incoming air is accurately measured before entering the engine. A deteriorated or damaged gasket can allow unmetered air to bypass the system, leading to vacuum leaks, poor idle quality, reduced engine performance and inconsistent fuel mixture.

Replacing the gasket whenever the intake system or throttle body is removed is recommended to maintain optimum engine performance and prevent air leaks that can affect drivability.

Whether you're carrying out a routine service, rebuilding an engine or restoring a classic air-cooled Porsche, this OE Match gasket provides a reliable sealing solution for long-lasting performance.

What Does the Air Intake Pipe to Throttle Body Gasket Do?

This gasket forms an airtight seal between the air intake pipe and the throttle body.

Its primary functions include:

• Preventing unmetered air from entering the intake system.
• Maintaining correct intake system sealing.
• Supporting accurate air and fuel mixture.
• Helping ensure stable idle quality.
• Promoting smooth engine performance.
• Reducing the risk of vacuum leaks.

A properly sealing intake gasket is essential for efficient combustion and reliable engine operation.

Why Replace the Air Intake Pipe to Throttle Body Gasket?

Intake gaskets are continually exposed to engine heat, vibration and age, which can eventually cause them to harden, compress or deteriorate.

Common reasons for replacement include:

• Vacuum leaks.
• Hardened or brittle gasket material.
• Air leaks after throttle body removal.
• Engine rebuilds.
• Intake system servicing.
• Poor idle quality.
• Reduced engine performance.
• Preventative maintenance.

Replacing the gasket ensures a proper seal is restored and helps avoid future intake air leaks.

Symptoms of a Failing Intake Gasket

A worn or leaking throttle body gasket may result in:

• Rough or unstable idle.
• High or fluctuating idle speed.
• Hesitation during acceleration.
• Lean running conditions.
• Whistling or hissing noises from the intake.
• Reduced engine efficiency.
• Difficult engine tuning.
• Increased fuel consumption.

Replacing the gasket is a simple but important step in maintaining the performance of your Porsche's induction system.

Benefits

• Restores proper intake system sealing.
• Helps maintain stable idle quality.
• Improves engine efficiency.
• Reduces the risk of unmetered air entering the engine.
• Straightforward installation.
• Suitable for restoration and routine maintenance.

Why Choose OE Match Engine Gaskets?

OE Match engine gaskets are manufactured to provide reliable sealing performance, precise fitment and long service life. Designed specifically for classic Porsche applications, they help maintain the correct operation of the induction system while supporting smooth engine performance and dependable reliability. OE Match components are trusted by enthusiasts and professional workshops undertaking everything from routine servicing to complete engine restorations.

Intake manifold gasket 2.0/2.2 carburettor/injection/2.4 K-Jet
The intake manifold gasket forms a critical seal between the intake manifold and the engine’s cylinder head. Its job is to prevent air, fuel vapor, and combustion gases from leaking out where the manifold joins the engine. A good gasket ensures that the engine receives properly metered air and fuel, improving performance and efficiency.
Sold each, 6 required per vehicle.

Fits:
Porsche 911 S 1965 - 1973 (not Sportomatic)
Porsche 911  2.7L  1974 - 1977  911/83 engine

Diagram ref no 14

Without an effective gasket at the intake manifold, unmetered air can enter the engine or metered air can escape - leading to rough idling, poor fuel economy, and potential misfires. This gasket helps maintain consistent air charge delivery to each cylinder, supports stable combustion, and prevents vacuum leaks.

The intake manifold gasket operates in a harsh engine environment - exposed to heat cycles, vibration, and pressure changes. Over time, the original gasket material can harden, shrink, or deteriorate, leading to:
• Vacuum leaks and unmetered air entering the engine
• Poor idling or rough engine performance
• Decreased fuel efficiency
• Engine hesitation or misfire.
Replacing it with a fresh gasket restores proper engine breathing and helps maintain smooth performance and reliability.

Replace the intake manifold gasket if you notice:
•  Rough idle or unpredictable engine behaviour
•  Check engine light codes related to intake air leaks
•  Decreased fuel efficiency
•  Visible signs of gasket wear (hardening, cracking, deformation)
•  Anytime the intake manifold is removed during maintenance

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.
