3 Bar MAP Sensor

The Omni Power 3 Bar MAP Sensor provides precise pressure monitoring for turbocharged Subaru applications, delivering a 0.001-second response time for improved engine performance and boost control. Engineered with a silicon pressure sensor and thin film resistor networks, it maintains a minimum of 99% accuracy in temperatures ranging from -40 to 260 degrees Fahrenheit. The sensor is dimensionally identical to the stock unit and offers a direct plug-and-play installation for a clean, OEM-style appearance. Its true linear 0-5 volt scale ensures reliable operation across varying altitudes without the need for constant re-tuning, helping to prevent the idle and drivability issues often associated with inaccurate pressure scaling. Compatibility is specific to 2004+ Subaru WRX and STi models. As an upgraded performance component, this sensor requires an engine management system for proper ECU recalibration before operation. It is not intended as a stock replacement sensor for naturally aspirated vehicles.
