Porsche 997 MAF Part Number: Complete Guide to Finding the Right Sensor

If you own a Porsche 997 and suspect a failing mass air flow (MAF) sensor, you need the correct part number before buying a replacement. The MAF sensor measures the amount of air entering the engine and sends that data to the ECU to adjust fuel delivery. A faulty sensor can cause rough idling, hesitation, poor fuel economy, and even a check engine light. Using the wrong part can lead to drivability issues or no improvement at all. This guide covers the correct Porsche 997 MAF part numbers for both the 997.1 (2005–2008) and 997.2 (2009–2012) generations, including Carrera and Carrera S variants.

Porsche 997 MAF Sensor Overview

The MAF sensor on a 997 is located in the intake duct between the air filter box and the throttle body. Porsche used Bosch sensors across all 997 models. The sensor itself is a hot-wire type that is sensitive to contamination from oiled air filters or dirt. Over time, the wire can become coated, causing inaccurate readings. The part number is stamped on the sensor housing – usually on a white or silver label. You can also find it in your owner’s manual or by searching online parts catalogs with your VIN.

Signs of a Failing MAF Sensor

Common symptoms include:

• Check engine light with codes like P0101, P0102, or P0103
• Rough idle or stalling
• Hesitation during acceleration
• Reduced fuel economy
• Black smoke from exhaust (rich mixture)
• Lack of power

If you experience any of these, diagnosing the MAF sensor is a good first step. You can clean it with a dedicated MAF cleaner, but if the sensor is old or damaged, replacement is the best course.

Correct MAF Part Numbers by Engine Type

The 997 had several engine variants, and the MAF sensor part number differs between the 997.1 and 997.2. Always confirm with your VIN before ordering, as there can be supersessions.

997.1 (2005–2008)

The 997.1 uses the M96 engine (3.6L in Carrera) or M97 engine (3.8L in Carrera S). Both typically use the same MAF sensor, though some early 2005 models may differ. The most common OEM part number is 997 606 010 00 (Bosch part number 0 280 218 124). This sensor is a direct fit and is used on both the 3.6L and 3.8L engines. It is a rectangular sensor with a five-pin connector.

Some aftermarket brands like VEMO and Pierburg also make replacements, but the Bosch sensor is the most reliable. Be wary of cheap no-name sensors; they often have poor calibration and can trigger error codes.

997.2 (2009–2012)

The 997.2 received direct injection engines (3.6L DFI and 3.8L DFI). The MAF sensor is different from the 997.1. The OEM part number is 997 606 012 00 (Bosch part number 0 280 218 149). This sensor has a slightly different housing and connector orientation. It is also a five-pin Bosch unit but should not be substituted with the 997.1 sensor.

Note that the 997.2 Turbo and GT3 models may use different sensors, but this guide focuses on the Carrera and Carrera S. For Turbo models, refer to your specific VIN or consult a Porsche parts specialist.

How to Verify Your Part Number

1. Look at the sensor itself. The part number is printed on a sticker or molded into the plastic.
2. Check your vehicle’s VIN on a Porsche parts site like the official Porsche Tequipment or an independent retailer’s VIN decoder.
3. Contact a Porsche dealer with your VIN – they can confirm the correct number.

Where to Buy the Correct MAF Sensor

You can purchase the MAF sensor from several sources. Avoid generic platforms that may sell counterfeit parts. Stick to reputable automotive parts retailers.

• Porsche dealership: Guaranteed OEM, but typically the most expensive option. Price varies but expect $200–$350.
• Specialty Porsche parts suppliers: Companies like FCP Euro, Pelican Parts, and ECS Tuning carry genuine Bosch and OEM sensors. They often provide lifetime warranties and detailed fitment notes.
• Local auto parts stores: Some carry Bosch sensors, but availability varies. Be sure to confirm the part number matches your engine.

Aftermarket alternatives from brands like NTK or VEMO may be cheaper, but they are not always plug-and-play. Some owners report needing to clean or adapt the sensor. For trouble-free replacement, stick with Bosch.

How to Replace the MAF Sensor on a 997

The replacement is straightforward and can be done in about 15 minutes with basic tools.

1. Disconnect the negative battery terminal – optional but recommended.
2. Unplug the electrical connector from the MAF sensor by pressing the tab and pulling.
3. Remove the air intake duct that connects the air filter box to the throttle body. This duct typically has two hose clamps. Loosen them with a flathead screwdriver or socket.
4. Unscrew the two Torx screws (usually T20 or T25) that secure the MAF sensor to the duct. Gently pull the sensor out.
5. Install the new sensor in the same orientation. Replace the screws and tighten to about 2.5 Nm or hand-tight.
6. Reattach the intake duct and tighten the clamps.
7. Reconnect the electrical connector and battery terminal.
8. Start the engine and let it idle for a minute. Then take a test drive. The check engine light should stay off if the sensor was the issue.

If the light returns or drivability problems persist, the fault may be elsewhere (vacuum leak, fuel system, etc.).

Frequently Asked Questions

Can I clean the MAF sensor instead of replacing it?

Yes, you can try cleaning with a dedicated MAF cleaner spray. Remove the sensor, spray it on the wire element, let it dry, and reinstall. This can fix mild contamination but will not fix a damaged sensor.

Do all 997.1 models use the same MAF part number?

Most do, but there are exceptions, especially for early 2005 cars and certain special editions. Always check your existing sensor or VIN.

Should I buy OEM or aftermarket?

OEM (Bosch) is the best choice for a direct replacement. Aftermarket sensors from known brands can work, but they may require adaptation. Avoid unbranded cheap sensors.

Are the MAF sensors for 997.1 and 997.2 interchangeable?

No. The 997.1 sensor has part number 997 606 010 00 (Bosch 0 280 218 124), while the 997.2 uses 997 606 012 00 (Bosch 0 280 218 149). The connectors may physically fit, but the calibration is different, leading to poor performance.

Final Recommendation

For any Porsche 997 owner replacing a MAF sensor, the safe choice is to purchase the genuine Bosch sensor matching your specific generation. For 997.1 Carrera and Carrera S, get the Bosch 0 280 218 124 (OEM 997.606.010.00). For 997.2, get the Bosch 0 280 218 149 (OEM 997.606.012.00). Confirm with your VIN before ordering. Avoid the temptation of a cheap online deal – a faulty sensor can cause drivability headaches that cost more in time and frustration. Stick with a trusted supplier and you’ll have your 997 running smoothly again.
