no offence,,,,,,, but anyone that would pay $174 dollars for an oil filter has got waaaaaaaay more money then sense. 
Well, I'm sure that most of us here could be accused of having more money than sense at one time or another. Hell, if I had more sense than money I probably would'nt be riding a motorcycle, so I am thankful for that affliction.
First, to answer Jester's fitment question. My buddy has an '08 SERK with a 110, he bought the same model that I have on my '03 SERK, and it fits fine.
I have had the K & P filter for some time now, and have gone through three or four oil changes with it. Here are my pros and cons...
ConsNone that I can see
ProsLooks cool
Provides some measure of additional cooling (you 110 owners should love that)
It is a permanent filter, never have to buy another one (hey, maybe I do have more sense than money!)
It very easily comes apart for cleaning and you can visually check for bits of metal or other signs of engine trouble.
I love it, most of my riding buddies have it and they love it too. And the guy with the 110 really loves it. Oh, and I bought it from a local indy and pait $150 for it (DAMMIT, more evidence of good sense). O.K., I'm off to count my money.
