Just wondering if u guys ran your stock filters without the precleaner sleeve... does this matter?

 

shouldnt matter with performance but will allow your filter to get dirty and need replacement sooner.
I use a K&N with an Outerwares (basically the same as polaris prefilter).

 

I run a K&N also, and use the Polaris prefilter....I had the prefilter when I put the K&N on, so used it.....also tried Uni-filter, but like the K&N better....

 

thanks for the replys.. i think im gonna run without the sleeve from now on

i almost bought a K&N but i figured with it being all powered snow i would just get the stock one for 12 bucks and wait till summer for the K&N

 

If your not running in dusty, dirty or sandy conditions you should be fine without it but I see no need to run without one because it shouldn't hamper performance at all and they are water resistant and keep the filter cleaner longer.

Also the K&N will save you money in the long run being cleanable/ reusable and will add some performance gains being freer flowing.
Just IMHO.
