Well i've done some searching and only turned up that the 303 is for 2nd gens and the 204 for 3rd gens for clearance purposes. I've been using the 204 for my oil changes with no problems. I was wondering if i'd get any more benefit out of using the 303 which is 10mm longer or if it doesn't really matter. Thanks.

K&Ns don't really filter oil that well anyways, well compared to any of the quality filters. If you are asking if they house more filter material, you won't know till you cut two apart. In many cases filter length has nothing to do with how much filter material is in the filter itself.

I don't know of another filter for our bikes that has a hex end. The hex end usually just is a good way for people to over tighten their filters anyways. I prefer clean oil over a gimmicky nut.

I'm using Amsoil filters on my bike. The K&N oil filters, filtration wise, are about the equivalent of a cheap Fram filter. So it filtering the oil, but it makes that nut on the end awfully expensive. I've just never been a fan because it's generally 3x the price of the cheap filters, but doesn't filter any better. If I pay more for a filter, I want it to filter my oil better.

K&N used to have their ratings on the box, same ratings as a Fram. Well behind WIX, Mobil 1, the "nicer" filters. Pretty much no filters have real ratings on the box anymore, now there are so many ways to "fudge" the numbers.
Bobistheoilguy.com is a good site for filters and lube research, however it can be very time consuming to find what you are looking for there sometimes. As with anything you have to read multiple sources, and come to your own conclusions. I've seen a few argue that "nicer" filters clog quicker because of the fine particles they catch and then operating in by pass mode, but claim the K&N superior because it won't catch this stuff, but will operate longer because it won't clog by catching fine particles? Seems like a seriously flawed argument...
I've been getting the Amsoil filters from Bob here on the board for a while, the cages get WIX filters.
