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

Part #: OMN - MAP - STI15 - 3BR. Omni Power USA 3 & 4 Bar MAP (Manifold Absolute Pressure) sensors are a game - changer. They use advanced bipolar op amp circuitry with thin - film resistor networks in each microchip. A specially designed silicon pressure sensor calculates pressure changes on a true linear 0 - 5 volt scale and compensates for temperature. This means the 4 Bar MAP sensor stays at least 99% accurate from 32°F to 180°F across its scale. Unlike other sensors, there's no need to re - tune at different altitudes because of the true linear pressure - to - voltage scale. 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 sensors precisely calculate 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 without leaking, a - 40 to 260°F temperature operating range, a super - fast response time of 0.001 seconds from 10% to 90% of the pressure scale, automatic temperature compensation, true linear scaling for perfect drivability at all boost and vacuum levels, compatibility with all aftermarket engine management systems, at least 99% accuracy under all conditions, smoother engine operation, and a direct plug - and - play design for easy install. Each sensor is hand - assembled and quality - checked in the USA before shipping.

Using this Omni Power MAP sensor is a breeze. First, locate the stock MAP sensor in your Subaru WRX or STI. Since this sensor is dimensionally identical to the stock one, it's a direct plug - and - play. Just remove the old sensor and plug in the new Omni Power sensor. You don't need to worry about re - tuning at different altitudes. For best results, keep your engine in good condition. When it comes to maintenance, there's not much you need to do. But if you notice any issues like rough idling or poor drivability, check the sensor connections. Make sure the sensor is within its operating temperature range of - 40 to 260°F. Also, keep in mind that it can withstand over 130 PSI, so don't be overly concerned about normal pressure changes. And remember, this sensor is assembled and quality - checked in the USA, so you can trust its performance.
