Holley Sniper MAP Sensors

The pressure inside the intake manifold is an extremely important input to the engine control unit. Holley Sniper MAP sensors respond to changes in manifold pressures and relay the information to the ECU in the form of a voltage signal ranging from 1-5 volts. These replacement sensors will handle applications up to 25 lbs. of boost. Additional notes: * Utilizes stock attaching points * Sensor monitors manifold vacuum, varying output voltage to the ECU as a function of load placed on the engine—providing necessary data to control fuel enrichment
