I put an AirRaid Air Cleaner on my 2002 f-250 turbo diesel, nice that you can pull it and clean it, but.... when your climbing hills on the highway or under any kind of load, it sounds like one of those new jet engines that pulses, except the pulses are quick.. I can't begin to explain the sound, kind of a bwoop bwoop bwoop... and gets louder and faster as the rpms go up.. anyone else experience noise from the air cleaner? maybe it should be larger? or the plenum that feeds the turbo larger?
