Good quality, good price

Consistent quality with UNI
I've used UNI filters on many of my ATVs and they've always offered consistent quality. I can't wouldn't say that they've given any performance advantage or superior filtration, but they make an excellent replacement filter and have options for non-oem intakes. As far as longevity goes, I replace my filters after three cycles of cleaning and oiling, and they've never let me down in that time.

Uni Air Filter
I got this filter for our 19 Yamaha Wolverine X2 R-Spec Special Edition UTV. Fit is fine and works as designed. My dealer told me with the X2 having a secondary oiled air filter in the bottom of the air box make sure not to over oil the outer filter or the oil will drain off and plug up the bottom filter. I haven't had that issue but it doe smake sense.

Not worth it
This is a very good filter don't get me wrong. But they just do not last! After 2 cleanings these things fall apart. If they were cheaper I would give a better review, but the price and longevity just don't match... I've tried giving them a chance and just doesn't work out...

Awesome filter
I love uni filters. All I run on my crf250r crf150f and yz250f. They are very durable and high flow while still catching the debris. Just make sure to clean it and oil it very regularly. I do it every other ride unless it’s dusty then every ride. Air filter maintenance is one of the most simple and necessary things to do on any dirt bike. It’s a valve saver

Is it a direct fit or does it need a adapter?
A shopper on Sep 13, 2016
BEST ANSWER: On every bike we have had they have been a direct fit when ordered for that specific model. Most of our bikes are running the stock filter basket except my crf450 which has the aluminum Twin Air filter basket and the Uni ordered for stock application fit perfectly there too.
does the pre-filter need oiled?
A shopper on Feb 28, 2017
BEST ANSWER: If they need oiling the oil comes with it if I'm not mistaken.
Someone took the factory filter off of my 1998 kawasaki lakota 4 wheeler and I need the filter to hook directly to the carburetor. Will it fit like that?
A shopper on Mar 11, 2017
BEST ANSWER: No, this filter is designed to fit in your factory air box. There are universal filters available that you may be able to measure the dimensions you need though.
I have a 2014 Honda trx 400. Will a 1999-2009 fit? I ordered for 2014 and that's what they sent me. Thanks
A shopper on Sep 22, 2016
BEST ANSWER: Yes, they're the same filter. It will fit 1999-2008 TRX400EX, 2009-2014 TRX400X, and 2004-2005 TRX450R.
Does this filter do good on dirt roads?
A shopper on Aug 18, 2016
BEST ANSWER: Yes, this is a great filter for off-road machines.
Are the dual layer filters glued/bonded together or separate?
Emmanuel R on Jan 27, 2019
BEST ANSWER: I can separate mine. In others words they are two different pieces.
What micron does it filter down to?
Brian K on Jan 9, 2017
BEST ANSWER: I believe down to 4 microns
Will I need to dyno or tune for this filter. I have a 03 400ex?
A shopper on Mar 31, 2017
BEST ANSWER: No this filter is a direct replacement but it does come un-oiled so make sure you oil it before use.
Can this filter be used as a filter for the clutch?
DEL S on Nov 15, 2016
BEST ANSWER: If it matches the intake tube size. I would clean the oil from the filter so that it will not lube or attack the belt system. The system most likely does not have the negative pressure overcome the filter being coated by fine particles which would stick to the oil, but not harm the belt system. The finer dust would blow through as normal, but the bigger coarser debris would be blocked.
Is this a direct bolt on replacement of the stock air filter on a 2003 Rubicon or do you have to use the metal cage from the original filter?
Taylor J on Sep 19, 2016
BEST ANSWER: If your stock filter has the metal cage then you will need to use that metal cage as well.
Does this filter require the stock filter cage?
A shopper on Apr 5, 2018
BEST ANSWER: This filter does not require the stock cage it can be run without using a cage as the cage can restrict airflow into the carburetor. It might tend to collapse without the cage but as long as its oiled properly it should function as normal
Does this come with the frame(flat filter, no cage)? Asking for XR650R.
Jack L on Jun 20, 2019
BEST ANSWER: Miine came with a cage for my 84 XR 500R
Where can I get an adapter?
A shopper on Dec 20, 2017
BEST ANSWER: uni filters use your stock filter cage. once in a while they will come with a cage built into it for example on an XR600/XR650.
Can i use k and n #99-5000 air filter cleaning kit on my uni air filter?
A shopper on May 17, 2017
BEST ANSWER: The K & N Recharger Kit 6.5 oz Oil, 12 oz Cleaner is only to be used on K&N filters. I'm sorry for the inconvenience.
