A MAF sensor works by sensing how much a heated resistor cools. The
more
it cools, the higher the airflow. Since you know the cross section of the
MAF sensor, you can figure out the volume of air coming into the engine.
However, if the air is tumbling around inside the MAF sensor and not
flowing straight through it, you will get an inaccurate reading, since the
air may be moving very slowly over the sensor but moving quickly on the
edge, or vice versa.
On 5.0 Mustangs when people put large conical K&Ns on the air meter
they have been known to cause bad MAF readings because one side of the
filter
tends to be shielded by the inner fender panel causing turbulence into the
meter. The solution is put the filter away from the meter and connect the
two
with a smooth pipe with a straight shot into the meter.
