Uni air filters or K&N air filters?
One of these robust air filters systems
are in my near future. Can anyone give
me their advise on each one by experience?
What are the pros/cons of each. My application
is for my Sportsman 450's. Keep in mind I will
being doing trail riding, lots of dust and mud
where it can be found.
Much obliged!

Uni air filters or K&N air filters?
I have a UNI in my bike and a K&N in my truck. Power difference was minimal but it makes the intake a little louder under load. I was just sick of getting the paper filters wet at $30 a pop everytime I got into some water with the Scrambler, So when I got the new bike it went in first. Both K&N and UNI are good quality filters, but don't expect neck snapping acceleration after LOL

Before you buy you might want to check out this website. The difference in air flow between a stock paper filter, a K&N, or a foam filter is so minimal it isn't worth the added cost. A paper filter filters way better than either a K&N or a foam filter.

I used to run K&N, but not anymore.

Uni air filters or K&N air filters?
00XJ -
I checked out your link, and a good read.
I wonder two things here. First, what is the
long-term testing after these filters get really
mucked up, dirty beyond belief and/or corroded?
(Yea, I know everyone should be tidy on their
own maintance ends)
Secondly, what about the wet conditions like
mentioned before? Like going thru streams, rivers,
ponds, deep mud/water etc? If the paper type lends
itself to paper debris that could negatively effect the
engine then maybe the foam or K&N would be a
desireable choice? I don't know you all are the experts,
running these air flow/filtration systems on your quads.
Really good read though on the diff between air filtration
and air flow. Good info.!
I don't know maybe I am smelling another million dollar
innovatitive idea here, like maybe we can add the IONIC
Breeze technology into our air boxes to negative collect air
particules. Off course we would have to avoid shock
when wet, ouch!

That link to Bob Is The Oil guy was an excellent, excellent read. Thank you for posting!
After reading the air filtration study Bob did, I am still pleased running K&N filters on my four-wheelers. My reason for this is the expense of having to replace paper air filters that just filter a little bit better, sometimes every weekend in the summer. The expense would be great. I share Bob's opinions on foam filters, about them being tedious to service. It also appears like foam doesn't do a lot better than K&Ns anyhow.
Where this study should really open eyes is with those that run K&Ns in their cars and trucks. I've run a K&N in my "mudder", and a K&N in my Camaro for years. The "mudder" has a huge K&N filter and a K&N pre-charger. Due to mud and water splashing, I'd probably stay with the K&N on this particular vehicle. If I would have read this study beforehand, I probably wouldn't have bothered getting one for the Camaro.
For daily drivers in regular environmental conditions, I don't see any performance or filtration benefit in getting a K&N filter. I've always known the 10 HP claim was BS, but Bob is pretty crystal clear with his study as it pertains to the "daily driver" vehicle. Very little benefit...
Did anyone else learn anything?
