400 Kpa MAP sensor kit for boost pressures above 2 bar for all 2.5L TFSI Audi RS3 and TTRS engines. Since the standard sensors cannot process boost pressures above 2 bar, these sensors are absolutely necessary. The 2.5L TFSI engine has two MAP sensors, one before and one after the throttle valve. The kit contains both MAP sensors. Attention : The map in the control unit must be adapted to the 400 Kpa MAP sensor !
