Omni Power 3 Bar MAP Sensor Subaru WRX 2006-2007 / STI 2004-2021

Part #: OMN-MAP-STI15-3BR. Omni Power USA's 3 & 4 Bar MAP (Manifold Absolute Pressure) sensors are a game - changer. They feature advanced bipolar op amp circuitry with thin - film resistor networks on each microchip. A specially designed silicon pressure sensor calculates pressure changes on a true linear 0 - 5 volt scale and compensates for temperature. This ensures at least 99% accuracy from 32°F to 180°F. Unlike other sensors, there's no need for re - tuning at different altitudes thanks to the true linear scale. Competitors' sensors may lead to engine tuning issues, idle problems, poor drivability, and even engine damage. Omni Power 4 - bar MAP sensors can precisely measure boost pressure from 1 - 43+ psi while maintaining smooth OEM drivability at any boost level. It comes in an OEM - sized housing for easy installation and an OEM look. Key features include cases that can withstand over 130 PSI, a - 40 to 260°F temperature operating range, a super - fast 0.001 - second response time from 10% to 90% of the pressure scale, automatic temperature compensation, true linear scaling for perfect drivability, compatibility with all aftermarket engine management systems, high accuracy under all conditions, smoother engine operation, and direct plug - and - play installation. Each sensor is hand - assembled and quality - checked in the USA before shipping.

Using this Omni Power MAP sensor is easy. First, make sure your vehicle is turned off. Locate the old MAP sensor and remove it. Then, simply plug in the new Omni Power sensor in its place as it's a direct plug - and - play. Start your vehicle and enjoy the improved performance. As for maintenance, there's not much to do. Just keep it clean and check the connections regularly. When it comes to temperature, this sensor can handle a wide range from - 40 to 260°F, but try to avoid extreme conditions if possible. Don't worry about re - tuning at different altitudes, as the sensor is designed with true linear scaling. And always remember, this sensor is quality - checked in the USA, so you can rely on its performance.
