A1 CARDONE 74-51003 mass air flow sensor for the 2002-2012 Porsche 911 H6 3.6L, the 2005-2012 911 H6 3.8L, the 2011 911 H6 4.0L and other vehicles measures the air flowing into the engine. This remanufactured sensor sends airflow readings to the engine control management system.
- 100% re-soldering of critical components for solid electrical connections and no intermittent failures
- Tracks output curves and holds spec tolerances for accurate scan tool readings
- On-car vehicle validation routines check form, fit, durability and performance
- 100% tested with automated computer test equipment for full functionality
- Components rated to handle demanding temperature variations
Quick facts
- Part: A1 CARDONE 74-51003 mass air flow sensor
- Fits: the 2002-2012 Porsche 911 H6 3.6L, the 2005-2012 911 H6 3.8L, the 2011 911 H6 4.0L and other vehicles
- Condition: Remanufactured
A failing mass air flow sensor can show up as hesitation, stalling, poor fuel economy or poor engine performance. Before you replace the sensor, read the trouble codes with a scanner and look over the sensor element for damage or a burnt smell, because those same symptoms can come from other parts.
Fits
Besides the 911 engines named above, it fits the 2004-2005 Porsche Carrera GT V10 5.7L and is the mass air flow sensor for the 1997-1999 Porsche Boxster H6 2.5L and the 2000-2004 Boxster H6 2.7L or 3.2L. Every one of these takes one sensor.
