Product Information

Full details

The febi bilstein Mass Air Flow (MAF) Sensor (108947) is designed for automotive enthusiasts and technicians looking to maintain or restore engine efficiency through precise air intake measurement. This sensor delivers OE-quality performance by accurately monitoring the mass of air entering the engine, which is critical for optimizing fuel combustion. While this component offers high-quality sensing capabilities, it is essential to verify your vehicle's specific engine code and OEM part number, as compatibility can vary even within the same vehicle model years.

FAQs

How do I know if this sensor fits my car?

You must cross-reference your vehicle's OEM part number with the febi bilstein 108947 specification. Check your vehicle's service manual or consult a parts specialist using your VIN.

Can I clean the sensor if it gets dirty?

While the sensor is robust, avoid cleaning it with standard solvents. If cleaning is necessary, use only a specialized MAF sensor cleaner spray and allow it to dry completely before installation.

Does this sensor come with mounting hardware?

The product includes the sensing unit. Re-use existing mounting hardware from your previous sensor unless otherwise specified.

Why is the direction of the sensor important?

The sensor is calibrated for a specific flow direction; installing it backward will result in incorrect air intake data and poor engine performance.

What is the connector configuration?

This sensor utilizes a standard 4-connector interface to match factory wiring harnesses.

Troubleshooting

Check Engine Light remains illuminated after installation

Use an OBD-II scanner to clear existing fault codes. If the light persists, ensure the electrical connector is fully seated and clicked into place.

Engine continues to experience rough idle

Verify that there are no vacuum leaks in the intake hose downstream of the sensor and ensure the sensor is installed in the correct orientation.

Pros and Cons

Pros

  • Meets or exceeds OE-quality standards
  • Precise hot-wire sensing technology for better fuel efficiency
  • Reliable, exact-fit design
  • Essential for restoring engine performance and idle stability

Cons

  • Requires specific engine compatibility verification
  • Installation requires technical automotive knowledge
  • Sensitive electronic components require careful handling

Setup, Compatibility & Care

Before installation, disconnect the negative battery terminal to prevent electrical shorts. Locate the existing MAF sensor, typically found between the air filter housing and the intake manifold. Carefully disconnect the 4-pin electrical connector and loosen the mounting screws or clips. When installing the new febi bilstein unit, ensure the directional flow arrow on the sensor housing matches the direction of air flowing toward the engine. Do not touch the internal sensing element, as oils from your skin can cause inaccurate readings. Always verify your specific OEM part number against the 108947 reference before mounting.
