Product Information

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

Seal for intake manifold. Porsche 911 65-73 / 914-6

90110839104

Product Information

Seal for intake manifold.
Genuine Porsche OE intake manifold gasket. The intake manifold gasket sits between the intake manifold and the cylinder head. Its role is to create a tight, leak-proof seal that prevents unmetered air, fuel mixture, and vacuum leaks that can disrupt engine performance and efficiency. A properly sealed intake system ensures that each cylinder receives the correct air and fuel charge for combustion.
Sold individually, 6 or 12 required per vehicle - depending on vehicle model

Fits:
Porsche 911 E 1969 - 1971
Porsche 911 /L/TU/T
Porsche 911 T / 911 T-V
Porsche 911 T-E/E 1972 - 1973

Porsche 914-6 1970 - 1976

The intake manifold gasket plays a crucial role in maintaining proper air and vacuum flow to the engine. Over time and with exposure to heat and vibration, gaskets may become brittle, compressed, or degraded, which can result in:
•  Vacuum leaks
•  Rough idle and hesitation
•  Increased fuel consumption
•  Loss of engine efficiency.
Replacing a worn or damaged gasket with a Genuine Porsche OE part helps restore correct sealing, stabilises vacuum, and improves engine performance in classic Porsche applications.

When to replace
Replace this intake manifold gasket if:
•   There are signs of vacuum leaks or unstable idle
•   You notice hissing or intake noise from the engine bay
•   The gasket has aged, cracked, or deteriorated
•   You’re performing engine, manifold, or fuel system service
•   You’re restoring or maintaining a classic Porsche engine

Product Information

Seal for intake manifold.
This is a high-quality intake manifold gasket manufactured to replicate the original Porsche factory specification. It serves as a precise sealing component between the intake manifold and cylinder head on select classic Porsche engines, ensuring proper air and fuel delivery into the engine.
Sold individually, 6 or 12 required per vehicle - depending on vehicle model

Fits:
Porsche 911 E 1969 - 1971
Porsche 911 / L / TU / T
Porsche 911 T / 911 T-V
Porsche 911 T-E / E 1972 - 1973

The intake manifold gasket creates a tight, leak-free seal between the intake manifold and the cylinder head. Its primary job is to prevent air and fuel mixture leaks, maintain proper vacuum integrity, and ensure that each cylinder receives the correct charge of air and fuel during engine operation. Without a proper gasket seal, the engine may pull unmetered air, leading to rough running, poor fuel economy, and reduced performance.

Installed between the intake manifold and the engine head, this gasket:
•  Seals intake ports to prevent vacuum and pressure leaks
•  Maintains proper air–fuel mixture routing into combustion chambers
•  Reduces risk of external leaks that could allow contaminants or hot gases into unwanted areas
•  Helps the engine run smoothly with consistent idle, throttle response, and efficiency gaskets are produced using quality materials that resist heat, pressure, and chemical exposure typical of classic Porsche engines.

Over time, intake manifold gaskets can become brittle, compressed, or degraded due to heat, vibration, and chemical exposure. When a gasket fails:
•  Unmetered air can enter the engine, causing lean conditions
•  Rough idling and hesitation may occur
•  Fuel consumption can increase
•  Vacuum leaks lead to unstable performance

Replacing a worn gasket restores the correct seal, improves overall engine breathing, and helps maintain factory-spec performance.

Replace the intake manifold gasket if you notice:
•  Rough idle or unstable engine performance
•  Sudden decrease in fuel efficiency
•  Visible vacuum leaks or intake noise
•  During intake manifold removal for servicing
•  Engine overhaul or restoration

Seal set for intake manifold, SET OF 12. Porsche 911 65-73 / 914-6

90110839104/1KITX12

Product Information

Seal set for intake manifold.
The set includes 12 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 12

Porsche 911 / L / TU / T
Porsche 911 T / 911 T-V
Porsche 914-6 1970 - 1976

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
