Omni Power 4 Bar MAP Sensor 2006-2007 WRX / 2004-2021 STI | Fast Response | High-Accuracy MAP Sensor
Overview
The Omni Power 4 Bar MAP Sensor is a precision-engineered manifold absolute pressure sensor designed specifically for the 2006-2007 Subaru WRX and 2004-2021 Subaru WRX STI platforms. This sensor accurately measures boost and vacuum pressures up to 4 bar, providing critical data to your engine management system for optimal tuning and drivability. It is ideal for Subaru enthusiasts looking to support higher boost levels and improve engine response without sacrificing reliability or requiring frequent recalibration.
Built with advanced bipolar op amp circuitry and thin film resistor networks, the Omni Power MAP sensor delivers true linear scaling across the entire pressure range. This design ensures consistent, accurate readings regardless of temperature, altitude, or humidity changes. The sensor’s robust construction withstands pressures exceeding 130 PSI and operates reliably in extreme temperatures from -40 to 260 degrees Fahrenheit. Hand assembled and tested in the USA, it offers unmatched quality control and durability for demanding Subaru applications.
For Subaru owners, this sensor translates to smoother engine operation and better drivability under varying conditions. Its rapid 0.001-second response time—the fastest on the market—enables your engine management system to react instantly to pressure changes, supporting higher boost targets and reducing the risk of detonation or boost spikes. The direct plug-and-play design maintains an OEM look and fitment, making it a seamless upgrade for WRX and STI owners focused on performance and reliability.
