This Genuine Porsche vacuum hose is used on Porsche 928 models within the intake/vacuum hose system and is associated with the brake booster vacuum circuit.

Fits:
Porsche 928 S4  1987 – 1991
Porsche 928 GT  1989 – 1991
Porsche 928 GTS  1992 – 1995

Diagram ref no 12

This hose is commonly described as the hose from the left intake side cover to the brake venturi “Y”.

Functions
• Routes vacuum through the engine intake/vacuum system
•  Supports correct brake booster vacuum supply
•  Helps maintain proper vacuum assistance for the braking system
•  Connects the left intake side cover area to the brake venturi “Y” connection
•  Helps prevent vacuum leaks that can affect idle quality and engine running
•  Maintains correct factory hose routing and fitment
•  Replaces aged, brittle, cracked or leaking original vacuum hose
•  Provides OE Porsche fitment for the 928 vacuum system.

Why Replace This Part?
Vacuum hoses become brittle, cracked, hardened or loose with age and heat exposure. A leaking vacuum hose can allow unmetered air into the system, which may cause rough idle, poor running, hesitation or reduced brake booster vacuum performance. Replacing the original hose with a Genuine Porsche OE vacuum hose helps restore the correct vacuum circuit, supports brake booster assistance and keeps the engine vacuum system operating as intended.

When to Replace This Part
•  If the hose is cracked, brittle, split or hardened
•  If there is a vacuum leak or hissing noise
•  If the engine has rough idle or poor running caused by unmetered air
•  If brake assistance feels reduced or inconsistent
•  During intake, vacuum system or brake booster vacuum repairs
•  During engine bay restoration or preventative maintenance
•  When replacing old, non-original or incorrectly routed vacuum hose
•  Before recommissioning a Porsche 928 that has been stored long-term.

Where It Fits on the Car
This hose fits in the engine bay vacuum system of the Porsche 928. It is associated with the LH-Jetronic intake hose system and connects the left intake side cover area to the brake venturi “Y” / brake booster vacuum circuit. Parts diagrams show this hose as diagram reference no. 12 in the LH-Jetronic hose section.

Vacuum hose / Brake booster line
This OE Match vacuum hose / brake booster line is a replacement engine bay vacuum hose for Porsche 928 models from 1987 to 1995. It is associated with the LH-Jetronic intake hose system and is designed to match the original-style fitment and function within the brake booster vacuum circuit.

Fits:
Porsche 928 S4  1987 – 1991
Porsche 928 GT  1989 – 1991
Porsche 928 GTS  1992 – 1995

Diagram ref no 12

The hose carries vacuum from the engine intake system to the brake booster vacuum circuit. It connects the left intake side cover area to the brake venturi “Y” / brake booster vacuum line arrangement, helping maintain the vacuum supply required for brake servo assistance and correct vacuum system operation.

Functions
• Connects the left intake side cover area to the brake venturi “Y” / brake booster vacuum circuit
•  Carries engine vacuum through the engine bay vacuum system
•  Supports brake booster / brake servo vacuum supply
•  Helps maintain correct vacuum pressure in the brake assist circuit
•  Supports reliable brake pedal assistance
•  Replaces cracked, split, hardened, or leaking original vacuum hoses
•  OE Match replacement for Porsche 928 vacuum and brake booster system repair.

Why Replace This Part?
Vacuum hoses can become hard, brittle, cracked, loose, or split due to heat, age, engine bay conditions, and long-term vacuum load. A damaged brake booster vacuum hose can cause vacuum leaks, poor brake servo assistance, rough idle, running issues, or faults in connected vacuum-controlled systems. Replacing the hose helps restore proper sealing, reliable vacuum supply, and safe brake assist function.

When to Replace This Part
•  The vacuum hose is cracked, split, brittle, or perished
•  The hose is loose or no longer seals correctly
•  Vacuum leaks are suspected in the engine bay
•  Brake pedal assistance feels reduced or inconsistent
•  The brake booster / servo vacuum circuit is being repaired
•  The LH-Jetronic intake hose system is being serviced
•  The vehicle is undergoing Porsche 928 engine bay or braking system restoration.

Where it fits on the car
This hose fits in the engine bay vacuum system of the Porsche 928. It is associated with the LH-Jetronic intake hose system and connects the left intake side cover area to the brake venturi “Y” / brake booster vacuum circuit.

About Air Mass/Flow Sensors

Air Mass Sensors – Precision Airflow Measurement for Porsche Performance

Air mass sensors (also known as mass air flow sensors or MAF sensors) are critical components in your Porsche’s engine management system. They measure the exact volume and density of air entering the engine, allowing the ECU to calculate the correct air-fuel mixture for efficient combustion, performance, and emissions control.

At Design911, we offer a comprehensive range of genuine and high-quality air mass sensors for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each sensor is designed for precision accuracy, responsive measurement, and long-term reliability — ensuring smooth power delivery, optimal fuel economy, and consistent engine performance.

What Do Air Mass Sensors Do?

The air mass sensor monitors the flow of incoming air to the engine and sends data to the vehicle’s ECU (Engine Control Unit). Its main functions include:

  • Measuring air intake to calculate the optimal air-fuel ratio.
  • Ensuring efficient combustion for performance and emissions compliance.
  • Supporting fuel economy by adjusting fuel delivery based on driving conditions.
  • Maintaining smooth engine operation under all loads and temperatures.

A properly functioning MAF sensor ensures your Porsche delivers the responsiveness, efficiency, and precision it was engineered for.

Why Do Air Mass Sensors Fail?

Air mass sensors are delicate electronic components and can degrade over time due to contamination, wear, or electrical issues. Common causes of failure include:

  • Contamination from dirt, oil vapour, or air filter residue coating the sensor wire.
  • Electrical faults or corrosion in the wiring harness or connectors.
  • Sensor burnout due to prolonged high temperatures.
  • Air leaks downstream of the sensor causing incorrect readings.
  • Use of low-quality air filters or poor servicing introducing debris into the intake.

Symptoms of a failing air mass sensor include rough idling, reduced power, poor acceleration, increased fuel consumption, or an illuminated engine warning light.

Why Replace a Faulty Air Mass Sensor?

A faulty or inaccurate MAF sensor can severely impact your Porsche’s performance, leading to poor drivability, high fuel use, and potential damage to other engine components. Replacing it restores proper airflow measurement and engine efficiency.

Benefits of replacement include:

  • Restored throttle response and smooth power delivery.
  • Optimised fuel economy and emissions control.
  • Prevention of stalling, hesitation, or misfires.
  • Reliable, manufacturer-quality sensor performance and lifespan.

All air mass sensors supplied are made to meet or exceed exacting engineering standards, using advanced materials and sensor technology for precision airflow measurement and long-lasting durability.
