This particular block off plate is used for removing the water to air heat exchanger located in the intake manifold of the 1.4 TSI CAX 122 hp / 125 hp and 1.2 TSI CBZ engines.
The heat exchanger (watercooler) delete increases the airflow capabilities of the stock intake manifold of the CAX engine and allows the install of a front mount intercooler for lower intake air temperature.
