I am very happy with my Uni's.Simple to clean and re-oil, doesn't come apart if water touches it.

I've had ZERO issues with my K&N and prefilter. The intake is CLEAN every time I inspect it.....and it gets dusty as hell here.....

Are you talking about your rail or a atv I really liked the K&N but I don't need any damage done to my engine like a rebuild at the end of the season you know what I mean.

I don't run an air filter on my dragster. I'm talking about the one on my quad. You're not going to damage it and need a rebuild. I've heard so much bs about how bad they are....yet I run one in my pickup, my car, and my quad. A sign that the air filter isn't doing its job is dirt, debris, and other stuff inside the intake tract past the filter....I have yet to find ANYTHING past the filters......If it was such an issue with them, K&N wouldn't be in business. So far, 100k miles on my car with the filter....Two years of that (750 miles a week) in one of the dustiest areas in Colorado, Ft. Lupton, ZERO DIRT PAST THE FILTER.......NONE! There were days after work I'd have enough dust on the car you couldn't see out of the windshield....It's all farm/ranch land, and oil fields......we have a very dry climate here as well, and as some can attest, trails can get damned dusty, especially riding in a group.....same deal with my quad, ZERO DIRT PAST THE FILTER. One of the biggest issues I've seen with them is failure to maintain them properly. When people wash them they over-oil them and then some of the oil gets sucked past the filter, contaminates the MAF, and now you have a check engine light....(car applications). Simple solution, clean the MAF, reclean the filter, and oil it PROPERLY. Want to see actual data from how good or bad a filter is? Take an oil sample from your machine, send it in to get analyzed. This will establish a baseline for all future samples...then install the aftermarket filter of your choice, and send samples in with every oil change. If dirt is getting past the filter, it will show up in the sample as silicon (not silicone) and a few other minerals......

K&N Filter is a no-no especially on dusty trails.

Agree. The cool kids put overpriced K&N filters on their street machines believing increased HP claims. Simple fact is micron filtering size is too large for off road use, easy concept.

Their was a video somewhere on the web that took cement dust and used a vacuum cleaner to examine how well a foam, paper, and gauze filter work. I won't use a gauze on .my recreational vehicles that are subjected to extreme dust.

YMMV

R2C is the one I like the best.
No more buying countless paper filters or dealing with hard to wash out oil and no more dealing with putting the oil back on.
That oil is a mess ,gets on everything and is sticky.

R2C works has good has a paper filters or better and can be just blown out or a wash with something like Purple Power.
I have 2 of them so I have no problem washing one and letting it dry before the next time I ride.

I noticed a super fine dust film getting past my paper filters on my Sportsmans when I rode over the Memorial weekend. They were aftermarket paper and not OEM Polaris filters.

I bought R2C filters for them and rode this past weekend. On Tuesday I pulled the filters and they were pretty full of the super fine dust. The inside of the filters were absolutely spotless and the intake was completely clean and showed no evidence of fine dust making it past the R2C filter. I’m highly impressed with them. I washed the pre- filters and blew out the R2C filters and reinstalled them.

X2 on the R2C filters. They're a little pricey on the front end but will pay for themselves within a couple cleanings vs. OEM. Fine dust infiltration will kill your engine in a very short time. Engine rebuilds ain't cheap.

The pre-filter isn't cheap either.
