When to replace air flow sensor in Porsche Boxster?
If the old sensor that you removed is 996.606.124.00, then you need to replace it with the same part number (or have Porsche update your DME software to accommodate the newer style sensor: see Technical Service Bulletin 1/00 2445 Air Flow Sensor — dated 4-18-00).
Where are the mass air flow sensors on a Porsche Cayenne?
On a Porsche Boxster, put the convertible top in the service position, then remove the engine cover. Locate the mass airflow sensors. On this Porsche Cayenne, there are two mass airflow sensors mounted on the air intake hoses. On the Boxster, the sensor is located on the driver’s side right after the air filter housing.
How do you clean a Porsche MAF sensor?
Pay attention to the arrow that shows the direction of airflow. If you are cleaning your existing Porsche MAF sensor, make sure to spray it with a Mass Air Flow Sensor Cleaner. Tighten the Torx screws. If the screw holes don’t line up correctly, remove the Porsche MAF sensor and rotate it 180 degrees. Porsche MAF sensor fits in only one direction.
Why does my Porsche Boxster not have a MAF?
If the clamp on the throttle body happens to come loose and fall off, then the MAF will indicate almost no air being sucked through the intake, yet the engine will be sucking air directly from the engine compartment into the throttle body.
Where is the mass air flow sensor on a Porsche Boxster?
Shown here is the mass air flow sensor (MAF). The main sensor fits in a hole in the air intake right downstream of the air filter. The green o-ring seals the sensor to the intake tube (yellow arrow). If you’re having trouble with your MAF, you can try to resurrect it by cleaning it.

When did Porsche change the DME software on the Boxster?
Porsche updated the sensors in the Boxster in mid-2000 and also released a new version of the DME software that is a required update if you are going to use this new and improved sensor (see Porsche Tech Bulletin Boxster 1a/00 2445). Here is a chart that shows the differences between all of the sensors:
