PRO-M Mass Air Meter 80MM Standard Calibration 5.0L 1989-1993

The Pro-M 80 is their flagship mass air meter. It is by far the most popular mass air meter ever offered. It outflows larger diameter meters by a long shot, due to its bell mouth design, and because the sampling element does not protrude into the opening.

The patented 360 sampling design of the Pro-M 80 makes this meter the finest in the industry. No other meter provides a signal as clean as that of the Pro-M 80. It is, by far, the most accurate meter on the market. Don't settle for the copy produced by the other guys! It does not have 360 degree sampling. The Pro-M 80's 360 degree sampling allows it to "average" the air flowing through meter, resulting in a more accurate reading than any other meter available.
