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 3, 4, and 5 - Bar MAP sensors are top - notch. They use 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 means the 4 - Bar MAP sensor stays at least 99% accurate from 32°F to 180°F. Unlike other sensors, it doesn't need re - tuning at different altitudes because of its true linear pressure - to - voltage scale. Competitors' sensors can cause engine tuning issues with elevation changes, leading to idle problems, poor drivability, and even engine damage. The Omni Power 4 - bar MAP sensor precisely measures 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: 1. The cases can handle over 130 PSI without leaking. 2. It operates in a temperature range of - 40 to 260°F. 3. It responds from 10% to 90% of the pressure scale in just 0.001 seconds, the fastest on the market. 4. It has automatic temperature compensation. 5. True linear scaling ensures perfect drivability at all boost and vacuum levels. 6. It's compatible with all aftermarket engine management systems. 7. It's at least 99% accurate across the full scale range in all conditions, including temperature, altitude, and humidity changes. 8. It offers smoother engine operation, higher boost levels, and better drivability than competitors' turbo MAP sensors. 9. It's a direct plug - and - play for easy install and an OEM look, being dimensionally identical to the stock MAP sensor. 10. Each sensor is hand - assembled in the USA and pressure and function - checked for top - notch quality control before shipping. Applications: Fits 2004+ Subaru STI (Including 2015+).

Using the Omni Power 4 - Bar MAP Sensor is a breeze. It's a direct plug - and - play, so you can simply replace your old sensor with this one. Since it's dimensionally identical to the stock sensor, there's no need to worry about fitting issues. When installing, make sure the connections are secure. This sensor can handle a wide range of temperatures from - 40 to 260°F, but it's still a good idea to keep it away from extreme heat sources. There's no need to re - tune it when you change altitudes, thanks to its true linear scaling. For maintenance, you don't have to do much. Just keep it clean and check the connections regularly. If you notice any issues with your engine's performance, like idle problems or poor drivability, first check the sensor's connections. If everything seems fine, it might be time to have it professionally checked. This sensor is built to last, with cases that can withstand over 130 PSI, and it's hand - assembled and quality - checked in the USA before shipping, so you can rely on its performance.
