The actual cone filters of all of them are just about the same, there is no real difference there. The kits with tubes will help because of the straighter air flow(especially on a 91-94). K&N holds an advantage of being CARB certified, so if you live in a state with inspections concerning CARB certification, you need a K&N (or a K&N sticker stuck on whatever setup). This is the sole reason why K&Ns are expensive, not that they perform better, only because they are certified.
Jim, the 95 has a strange, big end on the intake tube, that is why you will find a lot of applications for 96-01, but not 95. Hopefully the kit you find will have an adapter piece to compensate for the size difference, but you may have to fab one up.
