Secondary Breather Filter
This breather filter incorporates a CNC adapter and simply plugs into the secondary air pump hose on your vehicle. A breather filter is required when installing the Carbonio intake on a 2.0TSI CBFA engine code or a MK6 2.5L with a factory air pump. This is also the same breather filter included with the USP A4/S4 intake system.
