What This Product Does:
- Transfers vacuum to control the air injection valve or related components
- Supports proper operation of the secondary air injection system
- Helps reduce exhaust emissions during cold starts
- Assists in improving engine efficiency and emissions compliance
- Ensures accurate system response through proper vacuum delivery
Symptoms Of Wear Or Failure:
- Check engine light (emissions or secondary air injection fault codes)
- Rough idle or unstable engine RPM
- Hissing or whistling sound from the engine bay (vacuum leak)
- Reduced engine performance
- Poor fuel economy
- Failed emissions test
- Secondary air injection system not activating properly
- Cracked, brittle, or collapsed hose material
- Loose or disconnected vacuum line
Why Replacement Matters:
- Replacing a worn air injection vacuum line is important because it ensures proper vacuum delivery to the secondary air injection system. Over time, heat and engine bay exposure can cause the line to crack, harden, or leak.
- If a vacuum leak develops, the air injection system may not function correctly, leading to check engine lights, reduced emissions performance, rough idle, and potential failure of emissions testing.
- Installing a new vacuum line restores proper system control, prevents vacuum leaks, maintains engine efficiency, and ensures the vehicle meets emissions standards.

Inlet Manifold Breather Line for Fuel Tank
Maintain the efficiency and reliability of your Porsche's evaporative emissions system with this Inlet Manifold Fuel Tank Breather Line. Manufactured to Porsche's exact original equipment standards, this factory-original breather line provides the precise fit, durability and performance required to safely transfer fuel vapours from the fuel tank EVAP system to the engine's inlet manifold.
Fits:
- Porsche 958 Cayenne Turbo V8 4.8L Petrol (500Hp) 2010-17
- Porsche 958 Cayenne Turbo S V8 4.8L Petrol (550Hp) 2010-17
Diagram ref no 4
The fuel tank breather line is an essential part of the evaporative emissions (EVAP) system. Instead of allowing fuel vapours to escape into the atmosphere, the system routes them to the inlet manifold, where they are burned during normal combustion. This improves emissions performance, supports engine efficiency and helps maintain the correct intake vacuum.
Over time, breather lines can become brittle, crack or develop leaks due to prolonged exposure to heat, fuel vapours and engine movement. Replacing a damaged breather hose with a Genuine Porsche component restores factory performance while ensuring maximum reliability and long service life.
What Does the Inlet Manifold Fuel Tank Breather Line Do?
The breather line connects the fuel tank evaporative emissions (EVAP) system to the inlet manifold, allowing fuel vapours collected within the charcoal canister to be safely drawn into the engine and burned during combustion.
Its functions include:
- Transporting fuel vapours from the EVAP system to the engine.
- Preventing fuel vapour emissions from escaping into the atmosphere.
- Maintaining correct intake vacuum.
- Supporting efficient engine performance.
- Helping reduce exhaust emissions.
- Assisting compliance with modern emissions regulations.
A properly functioning breather line is essential for maintaining both engine efficiency and environmental performance.
Why Does the Breather Line Fail?
The breather line is constantly exposed to engine heat, vacuum pressure and fuel vapours, which can eventually cause deterioration.
Common causes of failure include:
- Heat-related ageing.
- Hardening or cracking of the hose.
- Fuel vapour degradation.
- Vacuum leaks.
- Damaged hose connectors.
- Engine movement stressing the pipework.
- Wear during servicing or engine repairs.
Replacing worn breather lines helps maintain the integrity of the EVAP system and prevents unwanted air entering the intake system.
Symptoms of a Failing Breather Line
Typical warning signs include:
- Engine management warning light.
- EVAP system fault codes.
- Fuel smell around the engine or vehicle.
- Rough or unstable idle.
- Vacuum leak or hissing noises.
- Poor fuel economy.
- Reduced engine performance.
- Visible cracking or deterioration of the hose.
Replacing the breather line promptly can often eliminate emissions-related faults and restore smooth engine operation.
When Should the Breather Line Be Replaced?
Replacement is recommended when:
- The hose becomes brittle or cracked.
- Vacuum leaks are detected.
- Fuel vapour leaks are present.
- EVAP fault codes are diagnosed.
- The inlet manifold is removed during servicing.
- Carrying out preventative maintenance on higher mileage vehicles.
Replacing ageing breather hoses helps maintain reliable emissions system performance and prevents future vacuum leaks.

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.
