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

The Porsche Rubber Sleeve for Air Intake is a genuine OEM replacement part designed to provide a secure, airtight connection within the air intake system. Used on classic Porsche 928 (1978–1984) and select 911 SC (1978–1979) models, this rubber sleeve links rigid intake components while absorbing vibration and movement.
Sold individually, 6 or 8 required per vehicle - depending on vehicle model
Fits:
Porsche 911 SC 1978 - 1983
Porsche 928 4.5L 1978 - 1979 with Engine type: 2801
Porsche 928 4.7L 1983 - 1984
with Engine type: 2819, 2820 * USA, Canada, Japan models Only
Diagram ref no 10 (for 911) or 37 (for 928)
The rubber sleeve acts as a seal and flexible hose between rigid parts of the intake system (for example between the airbox, intake manifold, or distributor, depending on configuration). It ensures air travels properly without leaks.
Symptoms Of A Worn Out Sleeve:
- Rough idle or uneven running — because air is leaking in (unmetered air), messing up the mixture.
- Hissing or whistling sounds from under the hood, particularly around where the sleeve is located.
- Hard starting or hesitation when accelerating, especially if the leak affects air flow under load.
- Reduced performance or lack of throttle response.
- Possibly engine warning lights / codes related to airflow, air/fuel mixture, or vacuum leaks.
- Prevents air leaks which can lead to rich or lean mixtures, poor throttle response, lower fuel efficiency, and possible engine damage over time.
- Helps maintain smooth running and reliability of older Porsche engines, where leaks or perished rubber hoses are common weak points.
- Preserves engine health by ensuring the correct air/fuel ratio. Unmetered air can contribute to detonation or stress on components.
- Maintains OEM specification — using a correctly sized, good-quality rubber sleeve helps ensure fit, sealing, and durability.

This sleeve joins intake components and prevents unmetered air leaks. A proper seal supports correct air-fuel mixture control, smooth running, and reliable performance.
Sold individually, 6 or 8 required per vehicle - depending on vehicle model
Fits:
Porsche 911 SC 1978 - 1983
Porsche 928 4.5L 1978 - 1979 with Engine type: 2801

Installed between intake pipes/ducting components, the sleeve absorbs vibration and minor movement while keeping the intake tract sealed. It helps protect against vacuum leaks that can cause rough idle, hesitation, or fault codes.
Aging intake rubber can crack, harden, or split from heat and oil vapours, leading to air leaks and unstable engine running. Replacing worn sleeves restores proper sealing, helping maintain correct airflow measurement and drivability.
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

Air Inlet Hoses, Pipes & Sleeves – Durable Intake Components for Porsche Performance
Air inlet hoses, pipes, and sleeves are essential components of your Porsche’s intake system, connecting the air filter housing, throttle body, turbocharger, and intercooler. They ensure a smooth and sealed flow of air into the engine, supporting efficient combustion, responsive acceleration, and consistent performance.
At Design911, we supply a full range of genuine and high-quality air inlet hoses, pipes, and sleeves for numerous Porsche models that include 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each component is engineered for precision fitment, heat resistance, and airflow stability — helping your Porsche deliver the performance and reliability it’s known for.
What Do Air Inlet Hoses, Pipes & Sleeves Do?
These components channel filtered air through the intake
system to the engine’s combustion chambers. Their main functions include:
- Maintaining
airtight airflow between intake components.
- Reducing
turbulence and air loss for improved throttle response.
- Supporting
optimal air pressure for turbocharged and naturally aspirated engines.
- Protecting against contaminants that can reduce performance or cause engine wear.
In turbocharged Porsche models, these parts also help manage boost pressure, making them crucial to both efficiency and power delivery.
Why Do Air Inlet Hoses, Pipes & Sleeves Fail?
Due to their constant exposure to heat, vibration, and
engine movement, air inlet components can deteriorate over time. Common causes
of failure include:
- Cracking
or splitting from heat cycles and material fatigue.
- Oil
or fuel vapor contamination softening the rubber or plastic.
- Loose
or damaged clamps causing vacuum or boost leaks.
- Age-related
hardening leading to brittle connections.
- Excessive boost pressure stressing the hose in performance applications.
Symptoms of failure include hissing or whistling noises, loss of boost pressure, poor throttle response, rough idling, or a check engine light caused by airflow irregularities.
Why Replace Worn Air Inlet Components?
A leaking or damaged inlet hose can cause unmetered air to enter the engine, resulting in incorrect fuel-air ratios, poor performance, or even turbocharger strain. Replacing worn or cracked hoses and pipes ensures proper airflow, efficient combustion, and reliable performance.
Benefits of replacement include:
- Restored air pressure and engine response.
- Improved turbo efficiency and power delivery.
- Enhanced fuel economy and reduced emissions.
- Long-term reliability with manufacturer-quality materials.
All hoses, pipes, and sleeves available at Design911 are crafted from high-temperature silicone, reinforced rubber, or aluminium alloys for superior sealing, flexibility, and strength — ensuring dependable performance under demanding conditions.
