Omni Power 4 Bar MAP Sensor Subaru WRX 2006-2007 / STI 2004-2021 | MAP-STI15-4BR

Part #: OMN - MAP - STI15 - 4BR. Omni Power USA's 4 Bar MAP (Manifold Absolute Pressure) sensor is a top - notch device. It uses 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 allows it to stay at least 99% accurate from 32°F to 180°F. Unlike other sensors, there's no need to re - tune at different altitudes. Competitor sensors may cause engine tuning issues with elevation changes, leading to idle problems, poor drivability, and even engine damage. The Omni Power 4 bar MAP sensor can precisely measure boost pressure from 1 - 43+ psi while ensuring smooth OEM - like drivability at any boost level. It comes in an OEM - sized housing for easy installation and an OEM look. Key features include leak - proof cases that can withstand over 130 PSI, a wide - temperature operating range of - 40 to 260°F, an incredibly fast response time of 0.001 seconds from 10% to 90% of the pressure scale, automatic temperature compensation, true linear scaling for great drivability, compatibility with all aftermarket engine management systems, high accuracy under all conditions, smoother engine operation, and direct plug - and - play installation. It fits 2004+ Subaru STI (including 2015+).

Using the Omni Power 4 Bar MAP Sensor is easy. Just plug it in like your stock sensor, as it's a direct plug - and - play device. There's no need to worry about re - tuning at different altitudes. When it comes to operating, it can handle a wide temperature range from - 40°F to 260°F, but try to avoid extreme conditions if possible. For maintenance, keep it clean and free from debris. Since it's hand - assembled and quality - checked in the USA, it's built to last. However, if you notice any issues like engine performance problems, it might be time to check the sensor. Overall, this sensor will give you accurate readings and smooth engine operation for a long time.
