Gaskets
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
OE Match intake manifold gasket set of 6 for Porsche 911E and 911S models from 1969 to 1971. This complete set provides the six gaskets required to seal the intake manifolds to the cylinder heads, supporting correct air intake sealing and smooth engine running.
SET OF 6
Fits:
Porsche 911 E/S 1969 - 1971
Diagram ref no 27
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.

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

Air Inlet Engine Gaskets – Precision Sealing for Optimal Porsche Performance
Air inlet engine gaskets are crucial sealing components within your Porsche’s intake system. They ensure an airtight connection between the intake manifold, throttle body, and other air passages, preventing unmetered air from entering the engine. By maintaining proper air pressure and flow, these gaskets help your Porsche deliver smooth performance, efficient combustion, and consistent power output.
At Design911, we supply a complete selection of genuine and high-quality air inlet gaskets for various Porsche models, including 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each gasket is designed for precise fitment, high heat resistance, and superior durability — ensuring reliable performance and long-lasting sealing under all driving conditions.
What Do Air Inlet Engine Gaskets Do?
Air inlet gaskets serve as a critical barrier that ensures
only properly metered air enters your Porsche’s engine. Their functions
include:
- Sealing
joints between intake components to prevent air leaks.
- Maintaining
correct air-fuel ratios for efficient combustion.
- Preventing
contamination from oil, dust, and debris.
- Ensuring stable engine idle and performance by regulating airflow integrity.
A high-quality gasket keeps your Porsche’s intake system perfectly balanced, contributing to smooth throttle response, better fuel efficiency, and reliable power delivery.
Why Do Air Inlet Engine Gaskets Fail?
Exposure to extreme heat, pressure, and vibration gradually
wears down air inlet gaskets. Over time, they can lose elasticity and sealing
capability. Common causes of failure include:
- Thermal
expansion and contraction causing cracks or deformation.
- Material
fatigue from continuous heat cycling.
- Oil
or coolant contamination degrading gasket integrity.
- Improper
installation or over-torquing during servicing.
- Age-related wear and drying of gasket material.
Symptoms of a failing air inlet gasket include rough idle, vacuum leaks, hissing noises, poor fuel economy, or a check engine light related to air-fuel imbalance.
Why Replace a Faulty Air Inlet Engine Gasket?
A worn or leaking air inlet gasket can allow unmetered air into the engine, disrupting combustion and reducing performance. Replacing it restores proper air sealing, improving efficiency and reliability while preventing potential damage to intake components.
Benefits of replacement include:
- Restored airtight sealing for optimal engine performance.
- Smoother idle and improved throttle response.
- Enhanced fuel efficiency and reduced emissions.
- Long-term reliability with manufacturer-quality materials.
All gaskets from Design911 are made from premium-grade composites or multi-layer materials, designed to withstand heat, pressure, and chemical exposure — ensuring consistent sealing and performance for every Porsche model.
