Righto, My '98 A3 1.8T has what appears to be a heater element in the airbox. Presumably this is used to warm the air on cold starts until the engine warms up a bit? It's situated in the top half of the airbox and has two electrical connections. Can anyone confirm that this is what it's for? I'd like to stick some sort of CAI under the hood, not for any particular performance reasons, simply because the BMC CDA looks bling and Carbonio gives you a nice whooshy sound (i'm a chav at heart). Has anyone else done this and what did you do about the electrical connections to the heater thingy? Can they just be unpluged, taped up and put out of the way or are they gonna cause any problems if not connected to something?
