Information
Air mass / flow sensors.
Fits:
Porsche 996 3.4cc 2WD >>2001
Porsche 986 2.5cc >>2000
All NON E-Accelerator cars
A mass airflow sensor is used to determine the mass of air entering an electronically fuel-injected engine. The air mass information is necessary for the engine control unit (ECU) to calculate and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature and altitude, and this is an ideal application for a mass sensor

Information
Vacuum hose / Brake booster line
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.

Information
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.
