4bar Bosch Map Sensor (std vag plug connection)




Bosch 4bar map sensor. Used on Ignitron ecu.

Standard vag plug connector.


The MAP sensor is used to measure air pressure within the boost pipes of your engine, as well as measuring the air temperature.

The 4 Bar Map Sensor is commonly used when tuning the 2.0TFSi VAG Engines, as they have the higher reading of 4 Bar as opposed to the standard 2.5 or 3 bar, meaning higher boost pressures can safely be used.
