yes they are!
think of the downside of pipes with filters on the end of them and the serious dirt they get clogged with rapidly. Then ask which is the proper Cold Air Induction system. - I sell more than a few Large Green Filters for the likes of Carbonio, AEM, ABD induction kits cos their filters are blinded with shite and knackered. Good whennew, but degrade very fast in their low, inner wheel arch/wing locations.
Bollox as you put it mate. The CAI is a filter configuration, not weather its as good as other systems. CAI kits refer to kits with a pipe that moves the filter away from the heat not ones that bring cold air to it.
