30Pcs 9Mm X 8Mm Hole Car Fender Fir Clips Rivets and 1pcs 3 Bar Map Manifold Absolute Pressure Sensor 30 Pcs Car fender clips rivets and 1 pc. Manifold Absolute Pressure SensorThe MAP sensor is a true absolute sensor, which means that it will allow your engine management system to compensate for altitude accordingly. The pressure inside the intake manifold is an extremely important input to the ECU. A high-quality MAP sensor is critical for engine performance. These sensors will respond to changes in manifold pressure and transmit information to the ECU in the form of a voltage signal in the range. The 3 bar map sensors precisely calculate boost pressure up to 43.5 psi (58 psi absolutely) while allowing for smooth and repeatable idle performance.
