RZR air intake

Has anyone changed the intake system on their rzr? Has anyone hear heard of any dust getting through uni filters etc. on the 09 and newer machines? Any rebuilds yet on the 09's or 10's?

Dont run a unifilter on a 09 RZR-S
LT saw dirt in his intake tube....

Run the stock paper filter , with an outterware
on it. and you will have no problems.

when we got back from bell county
i checked my air filter. and it looked just
like it was just put in. Clean as a whistle....

Chris...

I agree. The UNI seems to let a little more past. I am running the stocker again with a prefilter to see how it does. Dodd has a cool setup on his RZR, and I think it was quite a bit cheaper than the DFR intake system. Some say the 09 does not need an upgrade. Some say they do. I have not changed the intake personally, so I cannot really comment on one versus the other.

Bush ran 1700 hard dusty miles with his stock 09 system and the original filter with not a speck of dust getting past it. Ive read countless posts of dirt getting in the motor with the uni and the KN, run the stock system and save your money.

if its not broke dont fix it!! my 09 had 1700 miles and no dust in the intake and i run in some very dusty areas. so there are no plans to change it on the new one. and without motor mods changing the intake will not give you much more power if any at all.

So are most of you just sticking to the paper filter that came with it? Quite interesting, and cheaper to purchase.

This is astupid question but I am assuming these are reusable after rinsing off?

yes rinse with water

I have outerware too.....

and they come in many colors besides yellow just be sure to order the one that is water resistant just as added measure

Ok should I be concerned? I have about 550-600 miles on mine with the unifilter. I changed my oil at 25 hours, 50 hours and it currently has 67 hours. I have I possibly damaged my engine?

check you intake , and see if you see any Dirt.....

Here's the problem with the UNI that a lot of people don't relize. It's a 2-stage filter.You have to turn it inside-out and oil the inside, not just the outside. A lot of people just spray the outside and think all's good, not good. You have to oil the denser media (inside) too, if you don't, your toast.

Pull off the uni and take a bright flashlight and look into the intake, it should be shinny and clean. If you see dust and dirt then UNI has let you down. You can pull the TB off and clean everything but if a lot got by then you may develop problems with loss of compression or oil consumption down the road.

You see that is just the thing, rzr does not have a filter problem, they have an air box desighn problem. They bring the air supply intake in and shoot it right at the mouth of the filter, instead of routing it to the back of the filter.
Outerware does keep the filter cleaner longer, but once again they (POPO)have done nothing about how to stop the very fine dust getting by the mouth of the filter!

I know it's not the question being asked, and I am not going to start a bunch of s--t here... BUT, I have an 08 RZR and did have plenty of evidence that dirt had entered my engine. The reason being, the (no bellows having, dried out, cheap rubber boot) actually slipped off the base of the TB. I did roll the machine with just a few hrs. on it, and the boot may have come off at that time. I had never gone on any of thr RZR sites or spoke to anyone about this issue, or I may have been able to save myself some grief if I knew what to watch for. At rebuild time (under full warranty) and after gathering information on this issue, I purchased an 09 boot for the dealer to put on as they replaced my top end. He commented to me how old and brittle the stock one was, like it was made of some type of inferior rubber that had dry rotted in just a few months. I also advise replacing the lid to the air box with a three latch lid rather than the two latch that is on there now. THIS HAS SOLVED MY PROBLEM AND I WILL ALWAYS USE A STOCK FILTER ON MY MACHINE. (The new replacement stock)

I know I am slightly off track here, but the reasons for these comments is to remind everyone no matter what year RZR you have, CHECK THE AIR BOX, BOOT AND TB CONNECTIONS I am sure that is what failed, not the filter itself. Hell my air filter looked like brand new (because no air ever went through it!!!! it went directly into the engine.)

Not true, the new filter has a new base ring that keeps it tight to the tube along with a foam spacer on the back end that puts pressure on it when the lid is snapped on so it can not be unseated and by the way the inner tube goes about 3-4 inches into the filter, so where the air comes into the box has nothing to do with what the original problems were which was a less efficient filter, as showtime said the TB boot was a major part of the problem and a 2 clip airbox lid. If you run the new filter, TB boot and 3 clip lid you will not have any problems. thousands of miles of dusty use in the updated units prove this.

You see, we have seen the dust already leaking by the 2010, new and updated air filter, it depends on which country of origin it comes from.POPO still has not fixed the problem, its in the air box.
But nether here nor there, if one keeps a close eye on what they have, they should not have aproblem. Or at least catch it soon enough so it doesnt cause to much damage.

Don, you are saying a 2010 is letting dust by with a stock filter?

That's why I bought yours Don. Thanks for your effort to make a great product that corrects what POPO is to damn sorry to fix!

Dodd, I do really like your setup. I did not know this is where you bought it.

Don, what is your price for one?

I am NOT bad mouthing polaris. I have just bought my second one(RZR). I love the damn things. I like sitting in rather than siting on. But the way they put a bandaid fix just makes me pissed. My shop has tested the air box four times now, one out of every six have failed.(we gather all the stock boxes that our dealer replaces with our box). Every time dlmachineinc.com, sells one , we email popo to try to get them to pay attention. They still have not replied!
To answer your question the air box that Dodd has on his rzr is $245.00 plus $20.00 shipping.
We (dlmachineinc.com) are NOT an aftermarket dealer!! Just a machine shop that has the ability to build any thing.
What I am saying is I work very closely with a few different manufactures, which in turn I see things that most dont.
