Hi I was going to put a k and n induction kit on my leon cupra 1.8t and noticed that there is another pipe connected to the air box.
Can anybody tell me what this pipe actually does. It runs down to the bottom of the engine at the front and it's a circular connection plugging into the air box below the mad sensor.
