Information
Air mass / flow sensors
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

Information
Reconditioned Air Mass / Flow Sensor.
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.

Porsche 993 C2 / C4 / Carrera RS 1995-98
