Product Information
The Porsche Air Intake Hose is a genuine OEM replacement that connects the air filter housing to the throttle body or intake manifold, ensuring clean and measured airflow reaches the engine. Designed to handle heat, vibration, and under-hood conditions, this hose maintains the smooth airflow necessary for proper engine performance.
Fits:
What This Product Does:
The air intake hose is a key component of the Porsche engine air intake system. It connects parts of the intake assembly, ensuring that clean, filtered air flows smoothly from the air filter housing into the throttle body or intake manifold.
Symptoms Of A Faulty Air Intake Hose:
Over time, rubber intake hoses can degrade due to heat, oil vapors, and engine vibration.
Warning signs include:
A damaged air intake hose allows unfiltered or unmetered air to enter the engine, leading to poor performance, potential engine damage, and inaccurate readings from the mass airflow sensor.
Replacing with a genuine OEM Porsche intake hose ensures:

Air Intake Hose.The Porsche Air Intake Hose is a genuine OEM replacement that connects the air filter housing to the throttle body or intake manifold, ensuring clean and measured airflow reaches the engine. Designed to handle heat, vibration, and under-hood conditions, this hose maintains the smooth airflow necessary for proper engine performance.
Fits:
- Porsche 928S2 4.7L 1985-86
What This Product Does:
The air intake hose is a key component of the Porsche engine air intake system. It connects parts of the intake assembly, ensuring that clean, filtered air flows smoothly from the air filter housing into the throttle body or intake manifold.
Functions:
- Directs filtered air into the engine for combustion.
- Maintains smooth airflow without leaks or turbulence.
- Designed to withstand heat, vibration, and engine bay conditions.
- Ensures proper air/fuel mixture for efficient combustion and performance.
Symptoms Of A Faulty Air Intake Hose:
Over time, rubber intake hoses can degrade due to heat, oil vapors, and engine vibration.
Warning signs include:
- Cracks or splits visible on the hose surface.
- Hissing or whistling noises under acceleration.
- Check engine light (CEL) due to unmetered air leaks.
- Rough idle, poor acceleration, or hesitation.
- Reduced fuel efficiency caused by incorrect air/fuel mixture.
A damaged air intake hose allows unfiltered or unmetered air to enter the engine, leading to poor performance, potential engine damage, and inaccurate readings from the mass airflow sensor.
Replacing with a genuine OEM Porsche intake hose ensures:
- Proper airflow and engine efficiency.
- Leak-free connection between intake components.
- Long-lasting durability with factory-correct fitment.
- Restored smooth performance and reliability.

Rubber Sleeve For Air Intake.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.
Fits:
- Porsche 911 1978-1983 3.0L / SC
- Porsche 928 4.5L 1978-82
- Porsche 928S 4.7L 1981-83 (USA, Canada, Japan Models Only)
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.

About Hoses / Pipes / Sleeves
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.
