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.

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.
