Overview of UNI Two-Stage Competition Air Filter - NU-4135ST

  • Uni-Filters two-stage design provides maximum airflow, superior filtration and increased engine protection
  • Two-stage design allows industrial or farm use ATVs to go longer before service is required, due to the coarse outer layer stopping the larger particles, and the fine pore inner layer giving the ultimate engine protection
  • Uni-Seal filters feature a unique grease groove that allows for an effective application of sealing grease while snugly conforming to the sealing surface of the airbox
  • The choice of top racing teams

Air Filter
Filter does not come with the oil that you need to make it work correctly. I wish that was in the product overview. That would save you having to make a second purchase and waiting for it to ship. I wish I would have got a K&N filter instead. I know those come pre-oiled. This product will work well I'm sure, just wish it came with the oil you need to use it. Order the oil to if you buy this filter. Hope this helps the next guy.

Works Great!!!
Worked great even came with the metal mesh inside the filter so it's a true plug and play application. Only down fall is it's NOT pre-oiled so u will need to purchase oil for it.

UNI Filter
Great product, makes the machine breath easier. Its easy to clean and re-oil. I work in the bush all day and it keeps out all the dust and dirt. All around good OEM replacment.

My quad can now breath.
This filter does a much better job then the stock plus its reusable. Fits perfect and my quad breaths easier. I would recommend.
