Our Speedfactory 4 Bar MAP sensors are equipped with cutting-edge technology to ensure precision and reliability. They feature a bipolar op amp circuitry, thin film resistor networks on each microchip, and a silicon pressure sensor to calculate pressure changes on an accurate linear 0-5 volt scale.

This unique design compensates for temperature variations, allowing the k20 map sensors to maintain high accuracy even in extreme conditions. They boast a minimum of 99% accuracy from 32 to 180 degrees F.

Thanks to their actual linear pressure vs voltage scale, there is no need to re-tune at different altitudes like other sensors require.

This means you can enjoy smooth OEM drivability without worrying about altitude-related issues at any boost level. Our Speedfactory 4 bar MAP sensors can accurately measure boost pressure from 1-43+ psi, making them versatile for various applications.

Not only do these sensors offer exceptional performance, but they are also designed for easy installation. They come conveniently packaged in an OEM dimensional housing, making installation a breeze and giving them an OEM look.

So whether you are a professional mechanic or a DIY enthusiast, you can rest assured that our Speedfactory 4 Bar MAP sensors will provide you with the accuracy and reliability you need.


  • 40 to 260 degrees Fahrenheit temperature operating range
  • Able to respond from 10% of the pressure scale to 90% of the pressure scale in .001 seconds (the fastest response time of any k20 4 Bar MAP sensor on the market).
  • Automatic temperature compensation.
  • True linear scaling for perfect drivability at all boost and vacuum levels.
  • Compatible with all aftermarket engine management systems.
  • Minimum of 99% accurate over full-scale range under all conditions, including temperature, altitude, and humidity changes.
  • It allows smoother engine operation, higher boost levels, and better drivability than competitors' turbo MAP sensors.
  • Direct plug and play for an easy install and an OEM look. Dimensionally identical to the stock MAP sensor.
  • Each sensor is hand-assembled, and pressure and function are checked in the USA for unparalleled quality control before shipping
  • Available in black or red
