- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
The set includes 6 intake manifold gasket pieces - enough to replace all applicable intake sealing locations when performing major engine or intake work on early Porsche. Intake manifold gaskets form the seal between the cylinder head and intake manifold. They prevent unmetered air leaks, maintain engine vacuum, and help ensure that the correct air-fuel mixture enters each cylinder.
SET OF 6
Fits:
Porsche 911 E 1969 - 1971
Porsche 911 T-E / E 1972 - 1973
Diagram ref no 8
Intake manifold gaskets create the seal between the intake manifold flanges and the cylinder head. They prevent unmetered air and vacuum leaks that can upset combustion, reduce engine efficiency, and cause rough running. Proper intake gaskets ensure that the correct air and fuel charge enters each cylinder for optimal performance.
Function. When installed correctly, these gaskets:
• Seal the intake manifold to the cylinder head to prevent air and vacuum leaks
• Maintain consistent airflow into the intake ports
• Support stable idle and throttle response
• Reduce risk of detonation, poor fuel economy, and rough running.
Over time, intake gaskets may become brittle or compressed from heat cycles and age. Replacing them - especially in sets during rebuild or service - helps restore proper sealing and engine efficiency.
Intake manifold gaskets are critical for proper engine breathing and vacuum integrity. Worn, hardened, or leaking gaskets can cause:
• Vacuum leaks and unstable idle
• Hesitation or stumbling under acceleration
• Poor fuel economy
• Increased exhaust emissions
• Difficulty tuning carbureted or fuel-injected systems.
Replacing these gaskets in a complete set ensures all surfaces are sealed correctly, improves engine smoothness, and reduces the risk of running issues often misdiagnosed as other mechanical problems.
When to Replace. It’s recommended to replace intake manifold gaskets when:
• Performing major engine service or a cylinder head rebuild
• Intake manifold has been removed or loosened
• You notice hissing sounds or rough idle
• Vacuum gauge shows unstable readings
• Rubber/composite gasket surfaces show cracks, compression set, or distortion
• Engine has high mileage or long service life

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.
