if you won't be riding in alot of really dusty conditions but more mud than no, i've noticed many times after only 120 miles of really dusty conditions, meaning 5-6 or mote atvs riding together in a group and it had not rained in a week that the OEM filters themselves were completely filled with dust on both my atvs.
You could try spraying a bit of oil on the OEM pre filter and the K/N and see how it works.
The k/n pre filter is about $23, plus u will need to buy the ´recharge ´ cleaning kit which is a spray bottle of cleaning solution and a spray bottle of oil, about $20 and will last years. Their cleaning solution works really well. You can probably order all parts from a Autoparts store if k/n is not offering free shipping but it usually does. I checked online and ur filter is same as all other years Polaris Sportsmans incase they don't have the listing for 2017 yet. Polaris has been using same filter since mid 1990's Sportsman models, Even the 1000's have same filter.
