The K&N PL-8715 is a drop-in replacement element for the 2015 Polaris RZR 900, built on K&N's oiled cotton-gauze, high-flow design. Because the element is washable, a rider can clean and re-oil it rather than buying a new filter at every service interval, and the manufacturer backs it with a K&N Million Mile Limited Warranty. The manufacturer's listing gives the element an inside diameter of 2.5 in (64 mm) and a height of 11.063 in (281 mm). Per the manufacturer's application list, it covers the 2015 Polaris RZR 900 875 and later model years through 2020.
The main reason to pay for this over a stock paper element is sustained airflow in dusty conditions. The manufacturer describes the filter as ideal for extended use in dirty and dusty off-road riding, and says it helps maintain clean carburetion at high altitude. Generally, no jet changes are required with just a K&N filter element. That matters for buyers who want a bolt-on upgrade without retuning the fuel system. Searches for "RZR 900 reusable air filter," "PL-8715 cotton gauze filter," and "RZR 900 dusty trail air filter" typically point to this exact element.
The manufacturer's application list includes the 2015 Polaris RZR 900 875 under part number PL-8715. The EPS variants are listed separately, and the years shown for EPS models on the manufacturer's page were 2017 through 2019, so confirm your exact model and year before ordering.
The manufacturer states that generally no jet changes are required when only the K&N element is installed. If other engine modifications have been made, the manufacturer's guidance on fueling adjustments should be followed.
Yes. The manufacturer describes the element as washable and reusable and backs it with a Million Mile Limited Warranty. Follow the manufacturer's cleaning and re-oiling instructions when servicing it.
Replacing this filter is an airbox service job rather than an engine modification. Per the manufacturer's service procedure for the RZR 900 airbox, put the transmission in Park and open the cargo box access panel, then clear dirt from the airbox area before opening it. Release the airbox cover straps, lift off the cover, and pull the old filter toward the passenger side. Inspect the cover seal and replace it if it is worn; the seal is part number 5815300. Keep debris out of the airbox while the filter is out. When reinstalling, hold the new element in place with your fingers while you seat the lid, because the manufacturer notes that some K&N filters are easier to install into the lid first.
