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
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.
Replacing my stock filter element with this and also using UNI 1" filter vents on my airbox have given my KLR650 a huge wakeup call. These small changes have improved performance more than considerably. I had no idea my engine had trouble breathing until I installed this.
