Fits:
Porsche 911 2.4 S / 2.7 RS 1972 - 1977
Diagram Ref No 12
What This Product Does:
- The intake pipe (or intake connection) is a critical component in the engine’s air delivery system: it connects the throttle body, intake stack or air intake system to the intake manifold of the engine.
- It ensures a smooth, sealed, correctly shaped passage of air (and in the case of injection, the air-fuel mixture) into the cylinder head, maintaining correct airflow, avoiding leaks or turbulence that could upset fuel/air metering or engine response.
- On the era of 911 referenced (MFI mechanical fuel injection), proper intake piping is important for correct function of the injection system, throttle response, and overall engine performance.
Symptoms Of Wear, Damage Or When Replacement Matters:
- Air leaks or a hissing sound around the intake pipe, which can upset the injection/air-metering system, cause poor running, unstable idle or reduced performance.
- Poor throttle response, hesitation or mis-firing — if the pipe is cracked, partially blocked, or has missing components, it can degrade engine performance.
- Cracks, corrosion, or broken mounting tabs visible on the pipe or its flanges — especially for older vehicles where plastic/metal parts have aged.
- Difficulty fitting or aligning connections between the throttle stack and manifold — if the pipe is out of shape or damaged, it may be difficult to achieve correct installation or clean sealing.
- Ensures correct airflow and engine performance: A damaged or sub-standard intake pipe can compromise air delivery, disrupt mixture control, and reduce engine efficiency or driveability.
- Improves reliability: Old or worn intake components can lead to leaks, performance issues or even engine damage (if mixture is upset or induction temperatures become erratic). Replacing with a correct part restores the system.
- Simplifies installation: Buying a “complete” intake connection (rather than patching multiple smaller pieces) saves installation time, reduces risk of missing parts, and ensures compatibility.
- Ensures fitment integrity: In older vehicles, mounting points may have degraded—installing a new pipe with correct flanges/hardware ensures everything aligns properly, reducing stress or potential leaks.

Diagram ref no 7.
This set of six intake manifold gaskets provides a complete gas-tight seal between the intake manifold and cylinder heads, ensuring that all air entering the engine follows the correct metered path through the CIS or fuel-injection system. By eliminating air leaks at the manifold flanges, these gaskets help maintain proper air–fuel mixture, support smooth idle and drivability, and prevent lean conditions that can raise combustion temperatures.
Over time, manifold gaskets naturally harden, shrink or crack from heat cycles, fuel vapour exposure and age. When this happens, the engine may draw in unmetered air, resulting in rough idle, poor cold running, lean mixture symptoms, hesitation or flat spots during acceleration. Vacuum leaks also make tuning more difficult and can lead to increased fuel consumption. Replacing old gaskets with a fresh set of six restores full sealing integrity, stabilises idle and mixture control, and helps the engine operate as intended.
When to replace
You should replace the full set of inlet manifold gaskets if:
• You are rebuilding or refreshing the top end of the engine.
• There are suspected vacuum leaks around the intake manifold.
• The engine shows rough idle, hunting, or lean-related symptoms not traced to other components.
• The existing gaskets are cracked, brittle, or oil/fuel soaked.
• You are upgrading, servicing or adjusting the CIS / intake system on a classic 911 or 930.

Information
Rubber sleeves for air intake.
An OE-Match air intake rubber sleeve set, consisting of six identical sleeves, engineered to replicate the fit, function, and durability of the original Porsche intake couplers fitted to the 911 SC. It seals and connects intake system components.
SET OF 6
Fits:
Porsche 911 SC 1978 - 1983
Diagram ref no 10
These sleeves connect and seal individual intake components, preventing unmetered air from entering the engine. By restoring proper intake sealing across all connection points, the set helps maintain correct air-fuel mixture, smooth throttle response, and consistent engine operation.
Installed between intake runners and associated air ducting, the rubber sleeves provide a flexible, airtight connection while absorbing vibration and engine movement. Working together as a complete set, they eliminate common vacuum leaks that can cause rough idle, hesitation, or lean-running conditions on the 911 SC.
On classic Porsche engines, intake rubber components are prone to hardening, cracking, and shrinking due to age, heat, and fuel vapours. Even minor air leaks can disrupt mixture control and drivability. Replacing all intake sleeves as a complete set ensures consistent sealing across the system and helps restore proper engine performance and reliability.
When to replace:
• Visible cracks, splits, or swelling in the rubber
• Loose fitment or air leaks at the coupling points
• Rough idle, hesitation, or lean-running symptoms (after inspection)
• During intake service or when replacing adjacent intake hoses/boots
• Excessive hardening or deterioration from heat/oil exposure

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
Fits:
Porsche 911 / L / TU / T
Porsche 911 T / 911 T-V
Porsche 914-6 1970 - 1976
Diagram ref no 10
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

About Air Intake & Injection
Air Intake & Injection
Design911 provides a comprehensive range of engine air intake and fuel
injection components for all Porsche models, from classic air-cooled 911s
to the latest turbocharged engines. These systems work together to deliver the
precise air–fuel mixture required for clean combustion, optimal power, and
long-term engine health. Whether you’re restoring a classic, repairing a
misfire, or upgrading for improved throttle response, Design911 offers OEM and
high-performance parts engineered specifically for Porsche engines.
What These Components Are
Air Intake Components
- Air
filters, intake manifolds, plenum chambers, and air
ducts supply clean, measured airflow to the engine.
- MAF
(Mass Air Flow) sensors and MAP sensors monitor incoming air
volume and density.
- Throttle bodies regulate air delivery based on driver input. Performance upgrades include high-flow intake systems, sport air filters, and cold-air intake kits.
Injection Components
- Fuel
injectors, fuel rails, pressure regulators, and high-pressure
pumps manage fuel delivery with precise timing.
Electronic
control units (ECUs) command the injection system for efficient
combustion.
- Classic models may use mechanical injection (MFI), CIS/K-Jetronic, or carburettors, all supported with specialist replacement parts.
What They Do in the Engine
These systems work together to ensure your Porsche engine
receives:
- The correct volume of clean air
- The correct amount of atomised fuel
- Perfectly
timed air–fuel ratios for performance and efficiency
- Smooth cold starts, crisp throttle response, and stable idling
- Optimal combustion, power output, and reduced emissions
Air intake and fuel injection are essential to both everyday drivability and motorsport performance.
Why Air Intake & Injection Components Fail
Porsche engines are high-precision units. Over time, their intake and injection parts can deteriorate due to:
Common Failure Causes
- Dirty or clogged air filters
- Air
leaks in intake pipes, boots, or manifolds
- Faulty
MAF / MAP sensors causing incorrect readings
- Carbon
buildup inside throttle bodies or intake tracts
- Failing
fuel injectors (clogging, misfire, incorrect spray pattern)
- Fuel
pressure issues from worn pumps or regulators
- Age-related wear in classic mechanical injection systems
These problems often cause rough idle, hesitation, power loss, poor fuel economy, or engine warning lights.
Why They Should Be Replaced
Upgrading or replacing intake and injection components
restores:
- Accurate air–fuel delivery
- Faster throttle response & improved torque
- Smooth engine performance & reliable cold starts
- Lower fuel consumption & reduced emissions
- Protection from further engine damage
Performance-focused drivers may also benefit from sport air filters, larger throttle bodies, and high-flow injectors to maximise power.
Design911 supports a wide range of Porsche intake and
injection needs, including:
- Porsche air intake replacement parts
- High-flow intake systems for Porsche performance upgrades
- Porsche fuel injector sets & injection repair kits
- MAF/MAP sensor replacements for Porsche engines
- Throttle
body repair parts for Porsche 911, Boxster, Cayman
Classic
Porsche
- CIS & MFI injection components
- Porsche turbo intake pipes & boost-related air delivery parts
- Air leak repair components for Porsche flat-six engines
