installing a free air filter

i'm thinking about installing a free air style air filter to replace the air box in the 4.0 ZJ. i've found one that i believe will work K&N part number RE-0910. i've found a place online that will sell it to me for a lil over 40 bucks. great deal! i just want to make sure that i'm getting the right filter and everything will line up correctly. i understand that i will have to rig something to support the base of the filter but i think i can figure out something. if you have done this mod let me know. love to have some feedback on results as well. thanks guys!

oh yeah here's the link to exactly what filter i'm looking at:

Oh, you mean the conical style. Fine idea, but make sure that you get the conical (cone), b/c the drop-in was dyno'd at no performance increase.. I have heard that K&N filters let in dangerous particles..but that's rumor, and probably false. Anyway, you would be lucky to gain 5 RWHP, but if that's worth installing the conical then by all means go for it if the K&N is a safe filter.

thanks dave. and to respond to your futureZJowner. the 5 HP increase isn't what i'm really in this for, although it will be nice. the increase in gas mileage will be really nice though. the reported sucking sound might be cool as well

These conical filters (like the 9" one I'd like to put on my Jeep) have a rubber 3" or 3.5" inlet. The flex-hose from the throttle body is also rubber, so you need some kind of sleeve inside to mate them together.

What would be a good sleeve to use? I considered PVC but it's so thick-walled that I think it's probably a restriction, if anything. Really just need thin-wall steel sleeve. Hmmm..., maybe if I find an old 3" or 3.5" diameter metal can (like they'd sell brake fluid or solvent) I can cut the ends off, file the edges and use that.

how did you support your's? (like some steel strap running to the wheel well or something?)
