Let me preface this question with, ‘this may be a stupid question’. I am looking at stage I air cleaners and most of the research that I have seen says to just pick the one that you think looks best, because there is not much of a difference between them in a stage I set up. For reference, I am going with the Harley tuner to keep my warranty for the time being. My question is this, is there much of a difference between the stock air cleaner and any of these hi-flow options? It seems silly to spend the money if I’m happy with the way that it looks and the difference may be negligible.
