SpeedFactory Racing 4 Bar MAP Sensor for K Series (1-43+PSI) center 5pc pie cut) Race MufflerSpeedFactory 4 Bar MAP (Manifold Absolute Pressure) sensors use state of the art bipolar op amp circuitry with thin film resistor networks built into each micro chip. Pressure changes are calculated on a true linear 0 5 volt scale via a specially designed silicon pressure sensor that also compensates for temperature changes. The unique ability to compensate for temperature changes allows our MAP sensor to remain a minimum of 99% accurate from 32
