UNI Two-Stage Competition Air Filter - NU-4134ST
  • Uni-Filters two-stage design provides maximum airflow, superior filtration and increased engine protection

  • The choice of top racing teams

Does this item fit a 2012 Honda rancher AT?
A shopper on Apr 2, 2017
BEST ANSWER: The unifilter website says it isn't for that year of atv and gives NU-4142ST as the part number for the 2012 rancher. Hope that helps.

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.

Fits great
I bought two of these for our Honda Foreman Rubicons so I don't have to wait for the original filter to dry after servicing. I chose these because they have the internal cage and clamp included with the filter. The UNI slipped right on for a perfect fit......good value.
