Description

The Holley 2.5 Bar MAP Sensor is engineered for GM LS-Series engines, offering precise manifold pressure measurements up to 25 psi boost. This sensor utilizes stock attaching points and delivers a voltage signal range of 1-5 volts to the ECU, ensuring accurate fuel enrichment control. Ideal for applications up to 25 lbs. of boost, it monitors manifold vacuum, varying output voltage to the ECU as a function of load placed on the engine. This sensor is a direct replacement for ACDelco Supercharger Pressure Sensor part number 12592525. ([holley.com](https://www.holley.com/products/electrical/sensors/parts/870021?utm_source=openai))
