BITOG did a pressure drop test and found a 0.14% air flow improvement with a K&N over the worst paper filter. BITOG may know about oil, but I value real world testing over lab stuff. I know I, as well as a few thousand other people, picked up 2mph and 2 tenths in the quarter as well as gaining 2mpg with a K&N in my Mustang GT.

IOwnCalculus posted:Just the filter, or the whole intake? I know on the LT1 F-body, the filter alone in the stock airbox was worthless, but the whole FIPK was worth its weight in gold. Just the filter. The cold air intake itself didn't do anything but make the filter incredibly hard to check (in the fenderwell behind the liner).

It seems like if you wanted a stand alone system that lets you manage every single detail and has an awesome support network you would just go with something proven like the F.A.S.T. XFI, Big Stuff 3, Motec, etc...
