I just got done installing the pro design pro flo air filter kit and i am very satisfied with the way the billet adapter lets the filter mount a lot better than stock. I realize that the filter cage that comes with the pro-design filter is much less restrictive than the stock cage. My question is, by the time you install the pro design (UNI) filter and the red pre-filter ( i have also chose to run an outerwear on top of the pre-filter) how can this filter system possibly flow better than just the stock filter???
