uni foam or k&n filter

klutchbuster400 · May 07, 2006, 09:42:33 PM

hey, talking to a buddy of mines,he thinks that uni makes better air filters then k&n. Since i really dont know much about either, whcih one is really better. He told me taht k&n blocks alot of airflow. I really dont know what to believe, i run a k&n and he runs a uni, so maybe he's just defending his stuff.
any input?

what do you mean outerwear?
what is that, something that covers the filter / air box?

an outerwear is just a thing that goes around the airfilter and acts like a pre filter which helps block out sand and acess dirt.

The outerwear is around 15, and depending on the model of bike, I would say your 400 would run around 40bucks.

If you do alot of trail riding, I would go with a foam filter. If you want strictly performance, and you clean your filter every other ride, go with the K&N. Plus, you have to buy the special oil to spray it down with after you clean it, along with the cleaner.

I personally don't like k&n filters for dusty off road conditions. I only use foam filters. I use k&n on my truck but not on the quad. My feelings are if it needs another filter around the filter it can't be too good.

ya know that does make alot of sense! but since my bike came with a k&n i might as well buy an outerwear sine it will most likely cost less then a foam filter.

I prefer foam, seems to trap the dirt, but that does make more sense for your situation

I think the foam filters are a better way to go. Just my opinion though.

i have a k&n with an outerweres, and i had to clean the filter like every other ride, but i got an airbox outerwares for 15 bucks and it helps alot, u can buy the cleaner and oil in a kit at advanced autoparts for 12 dollars

So your expensive ATV engine isn't worth the extra $15 for a foam filter. You can pay a little now or a lot later.

ummmm, i seriously doubt my engine will blow, or recieve much, if any damage becuase of the filter i use. Like anything if you take care of it then you'l be ok. i didnt say i wasnt going to clean the filter after buying an outerwear.
