This sensor measures the amount of air entering the engine’s intake system and sends this data to the engine control unit (ECU) so the correct amount of fuel can be injected. The OE Match sensor is designed to replace the factory-installed component used on Porsche 993 engines. It uses modern sensing technology to accurately detect airflow and transmit the information to the engine control system. This part is commonly replaced during engine troubleshooting or maintenance when airflow readings become inaccurate due to contamination or internal sensor wear.
Fits:
Porsche 993 C2 / C4 1994 - 1998
The sensor monitors the amount and density of air entering the engine and sends this information to the ECU. The ECU uses the signal to calculate the optimal air-fuel mixture required for efficient combustion, engine performance and fuel economy.
If the sensor fails or sends incorrect data, the engine may run too rich or too lean, leading to poor performance or increased fuel consumption.
Function
• Airflow Measurement: Detects the mass of air entering the engine intake
• Fuel Control: Helps the ECU determine the correct fuel injection quantity
• Engine Efficiency: Supports optimal combustion and fuel economy
• Performance Stability: Maintains smooth engine operation and throttle response
MAF sensors are exposed to intake airflow, contaminants and heat, which can gradually affect sensor accuracy. When the sensor begins to fail, the engine control unit may receive incorrect airflow data, causing rough running, poor fuel economy or reduced engine performance. Replacing the sensor restores correct air-fuel mixture control and ensures the engine operates smoothly.
Consider replacing the air mass flow sensor if you notice:
• Check engine light related to airflow or fuel mixture
• Rough idle or engine hesitation
• Poor fuel economy
• Engine running excessively rich or lean

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.
