Cheers for the reply.Do you know if the K&N is an oily filter or is it dry.
Got a feeling that AWX denotes the engine code.I think Bluefox has a Skoda Fabia VRS so it's pretty much the same engine as the 130 ASZ found in the Golf (as far as I'm aware!)Incidentally I've got a 130 and just use the standard filter; seems fine with that; both rolling roads I've been on show her to be putting out 144 and 140 (obviously take the results with a pinch of salt!)
