Don't sound good for the 09 RZRs either

Just cut some plastic to close off the lower section then glue it in and cut the hole for the k&N. You would have do it to use that kit you showed too. Then you will get more air into the system and it will be cleaned twice before it goes in the motor. If your system has no leaks ( and mine will be checked from end to end and joints sealed with silicone) then there is absolutely no way in hell dirt will get in the motor. This is all overkill on mine as i firmly believe after reading about the new filter and other improvements mine will be fine, but this way im sure it will. I bet the new stock filter is even better than yours if you believe what polaris says about it.

This is what Polaris says about the problem and the up grades;


Hopefully, the following will help clear up some areas of concern for current RZR owners. The ultimate goal is to have every current RZR owner happy with their machine. PRC will continue to work with both Polaris and RZR owners until everyone is satisfied that the fix works for their riding conditions.

The issue with dirt getting into engines was first discovered last summer. Not long after this began to happen, Polaris issued a bulletin for airbox work to be performed by dealers. After completing this and changing the build of new units to reflect the updated method, Polaris saw warranty claims drop substantially. Still, there was a very small percentage of RZR owners that had problems. To Polaris, this was still too many and for PRC, we could tell that the issue was still alive and well. So, we went to the dealer show with hopes of finding more answers and to see what would be coming forth on the new RZR units any retrofit of older units.

The following is a summary of the Model Year 2009 changes.
--Better Throttle Body boot and connection
--Better sealed airbox lid. This was accomplished by adding a 3rd clip
--Hose clamp was replaced with a new injection molded air filter sealing ring
--New “closed cell” foam was placed around intake dog house
--The filter was changed to have 100% more pleated surface area and 2 ½ times the pleat depth. A new severe duty environment type media was spec’d.

All of these changes are positive moves and an attempt to get this issue behind everyone. There were many hours spent over the past few months to get to this point. According to the folks there in Vegas, this issue was tops on their list.

Below are some more points that were brought up.

--This new filter is NOT a snowmobile media. A water resistant coating that is used on the filter media of snow plow trucks to prolong their life in high snow dust environments, was utilized in the new filter.
--You can’t just throw a bigger filter on the RZR and be done with it. Large surface area filters look nice but must function. In that regard a new media was chosen for its exceptional efficiency and higher burst strength. What this last fancy statement boils down to is this; the baby powder sized, high velocity dust particles will stay on the outside of the filter where they belong. In this manner, the performance of the filter over time, is significantly improved.
--Many different intake locations were studied, including a front, remote mount. But, it was determined that the filter media construction had the greatest bearing on the desired outcome. If the media can’t perform in the environment it is put in, it doesn’t matter where you put it at. Plus, any mod/fix that was developed had to be compatible with existing RZR’s. If it were not, there would have been many frustrated owners, more than there are now.
--All changes are completely compatible with the 2008 model RZR. From what we are hearing, current owners should be satisfied and very happy with the improvements.

mine is a 09 without the TB boot and TB updates and I put the Dragon fire canister on before I did any real riding in the dirt and I have not had a spec of dust or dirt get past it. When I went to windrock and royal blue in OCT. the dust was so bad we almost had to keep quarter mile in between the 4 of us, it was bad you could not see infront or behind your own machine, I decided not to check my filter the whole week because I said to myself if this $500 filter/canister does not stop the dust nothing will. Once I got home the filter was pretty nasty but absolutely not one spec of dust has gotten by the filter, I have right around 510 miles and not a drop of oil used either. I also have nasty fine black dirt here in FL and it hasn't gotten past either, I am very confident in the filter now but I still check after every ride JUST IN CASE :D

my god it better for $500 bucks! I really never gave the stock one a chance so who knows it may have worked? I just didn't want to risk it, I also purchased a 4year extended warranty but I would hate to ever have to use it :evil:

Id say the new filter is even better than the one dfr or the others use after reading what went into its development. But if you are getting dirt into the airbox with the filter you need to do the upgrades in the link i posted, The cleaner the air you have going in the box for the filter to process the better.

How could you say that you don't even have the filter from the DFR I have both(and the new one from POPO) and it is DEFINITELY not as good as the DRF filter, there is no comparison, size alone it's still much larger and has twice the filtration, the DRF filter is from bob cats, and skid steers, those machines work in the nastiest, dustiest conditions on earth for hours at a time as a matter a fact a guy on my job site has one on his $65,000 skid steer and if it works on his expensive machine it should work on my $12,000.

I have seen all the upgrades, and all the hack jobs some guys are doing to there middle plastics, I was researching this long before you purchased your rzr,(that statement wasn't meant to be smartass at all, I just remember you were still riding the prowler back then)
Plus it's ok to get dust into the canister, just not past the TB, The size of the canister on the DRF alone dwarfs the stock one, there is plenty of room in there for clean air plus the cansiter/filter creates a swirling type of effect that actually forces the dirty air towards the front of the canister.

I could run my canister with the top off of it and it still would NOT suck dust, there is basically an impossible seal to pass once the filter is locked down with a BOLT and rubber seal on both ends, then the top is sealed with a rubber seal and another rubber seal bolt and the filter itself is WAY to THICK for any dust to get past the actually paper pletes.

Ok Maybe they will clean the air as good in some cases but i still dont think they are better being they are listed as being a "high flow performance filter" High flow means just that, you cant have super high flow of air without something like the super fine dust finding its way in with it. The new popo filter was designed especially for this issue from technology used in machines with a far bigger dust issue than bobcats or desert racers. The product info I read listed below says nothing about being used in dirt moving equipment it says used in racing in the desert. I also based my opinion on Bobby's problem where he is running the same dfr unit and was told by the dealer it was still ingesting dirt as well as several other posts on prc and rzr.net of others using it and still ingesting dirt. If yours is working that's great, but some don't and that's a fact. IMO now that a new filter is out and should do the job a 100% why spend 5 bills on a solution that might work and might not. Also another thing to consider is warranty, Polaris would not have to honor any clam of dirt in the motor of a 09 with the new up dates if someone has installed a dfr unit or another brand. Dont get me wrong, i think its great you fixed your issues before it ruined the top end im glad it worked for you.

DFR;
This is canister style intake system, the same found our our race cars in the desert. It is a full replacement for the factory intake system. 80% increased air flow as compared to single inlet filter systems. Inlet Ports give 80% Flow Efficiency, no oily foam outer required Velocity fins remove up to 85% of the incoming dust before it reaches the filter. No oil required on the filter element, which can cause damage to engine sensors. Filter element removes up to 99.99% of the remaining dust in the air before going into your expensive engine & components. Filter element is easily removed from either end. Filter end caps are machined from a single piece of high strength 6061-T6 billet aluminum. Not spun aluminum! Modular design, parts can be changed to increase or decrease the filter size. No drilling required to mount filter. Mounting clamps included..

It is a donaldson filter look it up, directly used in bobcats in skid steers, what makes it a high flow is the size of the filter not nessicarly how much air it lets in, it breaths much more because it is huge!!, if you had personally seen the filter and canister you would see what I mean, the whole thing is twice the size of the polaris's filter and canister.
If people are still experincing issues with the DRF it's because it must becoming from somewhere else, the DRF filter is to large and the rzr does not create enough suction for ENOUGH dust to pentrate the pletes. I also believe bobby's problem is not from the filter either, in my OPINION it's either crappy rebuild job or they should have replaced the bottom end as well.
The new air filter that polaris uses is also from industrial equipment, they did not design the filter,as DRF did not design theres either, these filters are taken from other machines that have proven to work in the past from the harshest conditions, keep reading the prcforum and you will see. And no matter what filter you have dust some how always finds it's way throught the filter, micro particals, I actually had a yamaha representative tell me this at my dealership, the engines are built to withstand certain tolerances of dust. there is no 100% way to keep the dust completely out of any one filter.

I agree if air gets in some dirt does too. I have seen the dfr unit, looks like a mini beer keg. LOL I have not seen the filter nor can i find a part number to look it up with, no doubt Donaldson makes good filters but the new polaris filter was designed for the rzr it is not a off the shelf filter designed for numerous applications. It has the new design clamp less seal that is said to stop all dust from getting by as well. I dont know about bobbys for sure just what the dealer told him since he did not look before taking it in. Could be they just said that to cover there ass.

We are finishing a performance 09 RZR today with dragon fire mods airbox,power comander,tru duel exhaust,clutch, and a few more. As soon as the boys in back finish I will post pics and vids.

I bet they are covering there butts, because think about how many people have had there engines rebuilt and even if they are still sucking dust it takes quite a few miles before some of them start going south, from what I have seen anyways.

Direct quote from the "Polaris guys"

Quote :

The Polaris engineer also shared lots of background of the media. They are now utilizing the same media that large snow plow trucks use. They were encouraged in that direction by the the actual filter manufacturer. Commercial snow plow trucks work in a constant hurricane of snow dust so no matter where the the air inlet is placed the snow dust finds a path to the filter. This media is designed to be covered in this dust yet not allow it to pass through. The new RZR filter is made from the same higher quality media. And as stated above there 100% more sq. in's.

now you tell me what goes through more dust a skid steer/bobcat that works in moving and lifting and clearing dirt/dust all day, or a SNOW PLOW TRUCK my old filter that came of off my rzr before the new filter was even out had the new clamp on it as well.

ON a lighter note how are you liking your new rzr???

On the clamp, that was on the old type filter, the new one has no clamp at all. As to which one gets more dirt from what ive read they say the snow blowers do, but you would think a dirt mover would. But yes i like the rzr although ive only ridden it around the yard. Im getting trail ready while its clean, hate putting new stuff on after its been all dirty

Well it's kind of a clamp it has a plastic ring around the end of it not a hose type clamp like the old one.

aren't you in tenn. or wv??? I cant believe you haven't gotten that thing on the trial yet! When i had mine up there it was absolutely amazing, you will see once you get on those off camber situations how much confidence you have going through them, thats were that lower center of gravity advantage really kicks in!! although I do have spacers and wheels/tires it did unbelievable, I swear it's like a mountain goat!!!

In Georgia 30 miles north of atlanta, 200 miles and 3 hours to windrock. Mine will be ready when i go, i have all the parts and slowly are getting them installed. SS112's, bighorns, 1.5 spacers, and i am doing the kn prefilter mod like this to the air intake first also.

oh man that thin is gonna do awesome!!

wish i had the coin for shocks like yours has!

the shocks really helped with the ground clearance, I have right around 10.75 in the rear and 11.5 up front, which really helped on the rocky sections at windrock.

I'm staying out of these discussions from now on

Gunny , stop being a tight wad. you dame well got the money
for some shocks.... Now come off with the coin.... :D

Chris....

As I understand it the throttle body was a source of leakage. I checked mine by starting it up and spraying a little bit of starting fluid around the boots. lucky for me the motor didnt rev up any.
