Genuine 4 Bar MAP Sensor (Boost Pressure Sensor)

You will need a 4 Bar MAP sensor to run most turbo upgrades to their full potential.

A MAP sensor rated to 4 bar will read 3 bar boost. This is because the MAP sensor is rated to an absolute pressure which includes atmospheric pressure of approximately 1 bar.

You always want headroom when it comes to the sensor so the ECU can see over-boost and correct it should it occur!

Important Information

Installation of this sensor requires immediate re-calibration of the ECU and must only be fitted when alongside a tuner who is ready to update the ECU. Replacing a 3 bar sensor for 4 bar without this re-calibration will cause over-boost, and may damage your engine
