Don't use K&N, great filters for cars (not in SouthWest). This biggest issue is the super fine dust/dirt that make it past them. IMO K&N are great race filters, but in dusty conditions you can't beat a good ole paper filter. Some are using the R2C filter, but I prefer the OEM for warranty purposes. Polaris will ask for proof of purchase on filters and if you have dirt in the engine and haven't been using OEM, good luck getting it covered.

 

Get the Polaris high performance filter made by Donaldson it has a blue hue to it and the sealing spigot is twice as long for a better seal then get a hose clamp and grease before installing
You can find these online or get direct from your dealer. And as stated above stay away from kn or oiled foam and or cotton filters

 

I do not recommend the use of a k&n on any rzr. I run stock paper filters on my machines.

Use the stock paper filter...

 

You may want to consider the R2C filter. We have sold hundreds. They filter better than the stock paper filter. They are serviceable/cleanable and dont need any messy oils.




let us know if you have any additional questions. We also carry the R2C filters for the RZR900S/Trail/XC and the RZR800/800S

 

We sold a ton of the RC2 filters without any complaints from our customers.

Another stay away from the K&N type filters guy here. I wanted serviceable so I went with the R2C filter from desert moldings.

 

I am probably only one who like the K&N.LOL

k&n vs. stock filter

I love K&N, just not on the RZR. I have buddies who run UNI as well on their Turbo 800's. UNI is the only wet filter setup I would consider with the greased pre-filter.

For those running a clamp, do not grease the connection as I've heard the filter tends to slide off coupling. You want the friction to hold it in. In my case I use K&N sealing grease on stock filter to help catch any fine dirt that gets up where the two meet.

 

now i wonder if they'll take it back unopened

 

I love k&n filters wash it and reuse it with an outerwear on it the only setup for the dunes. all the big sandcars and trophy truck guys run them with no issues but that is my 2 cents.

 

DON'T DO IT! Stay with the stock paper filter.....

 

I have been using k&n filters in my atv's for 30+ years never had any problems love them.

 

I use K&N on my ATV's but they are 2-strokes and will need topends long before dust would become an issue. I use them mostly because foams plug up to fast or are too large, and they don't make any decent paper filters that will fit in the confined space.

For the RzR the R2C seems like a great upgrade over stock, if I get dust in the engine it won't be due to the air filter, it's attached rock solid with the hose clamp and the filter has a lip. Beyond that there is a support arm to further prevent it from coming off. Went riding in a sand storm and had some very fine powdery sand getting was sucked into the airbox, right through the frog skins, like a little powdery dune right under the filter. Nothing noticeable got past the R2C filter though!

Stock paper one seems ok, but the R2C is certainly a step up. I would be replacing my stock paper one like every trip $$$

 

I use the Uni foam filter. It's a dual foam setup and works great! I've raced motocross for a zillion years and foam filters are the best thing going. It's a two stage filter w/ two layers of foam. Normally after a dusty ride, I can pull, clean, oil, and reinstall the outside layer only and I'm good to go.
Once after a particularly dusty ride using the OEM filter on my XP1K, I found fine dust in the intake, downstream of filter. I was none too happy. Last week I returned from a very, very dusty 500 mile trip in Baja with buddies. The outer layer of my Uni was disgusting. The inner layer looked as clean as the day I bought it. Of course, the intake was clean as a whistle and very happy.
It's a bit of a pain to clean and oil these these, but well worth the investment in time... IMO. Keep in mind, you will have to buy foam filter oil. I use the Uni brand. Uni cleaning solution isn't the greatest, so I first clean with a mild dish washing liquid, then use the solution. Works like a champ!
You can find these at Rocky Mountain ATV and I'm sure several other places.
Here is the Uni website. The filter for the '14 and '15 XP1000 and XP4 is the one on the left... Hope this helps...

Oh, one more thing. I have noticed absolutely no change in power or restriction to air flow. In fact, south of the boarder I hit 78 mph (according to my GPS) on a flat, dirt straightaway. Thought my dang helmet was going to blow off with my head in it!

 

Here is the filter at Rocky Mountain ATV/MC...

I would never run the kn filter, I have had many issues bc of those filters in the past. I only run the R2C Filters on my RZR's, not a spec of dust, silt or dirt in the intake. Truly the best filters I have ever run.
