Genuine GM 2 Bar MAP Sensor. Also known as Boost Solenoid, Pressure Sensor, M.A.P Sensor, Barometric Sensor, Barometric Pressure Sensor, Manifold Absolute Pressure Sensor, etc.
Installing a supercharger or turbo on your LSX powered vehicle? If your tuner recommends it you may need to use a two bar map sensor for your application. We offer the brick style (GM #12569241) as well!
Chevrolet Performance MAP sensors are high-quality, direct fit replacements for worn or malfunctioning MAP (manifold absolute pressure) sensors. These sensors accurately produce voltage or frequency as intake manifold pressure changes, and the computer uses this information to measure engine load so that the ignition timing can be advanced and retarded as needed. These MAP sensors are available to fit most GM engines, including the LS Series. They're built from factory-style materials and easily install in the stock location, so no modifications are necessary.
