The K&N PL-1710 is a reusable, oiled cotton-gauze replacement element that K&N developed specifically for the Polaris Ranger RZR 170 side-by-side. K&N's PL-1710 High-Flow Air Filter was developed specifically for Polaris' Ranger RZR 170 youth model side-by-side. Compared with a paper OE element, a cleanable, re-oilable cotton filter can be serviced again and again instead of being discarded. The manufacturer also states that no fuel management modifications are required to obtain increased performance, which keeps the upgrade simple. Owners on user forums warn that in very dusty terrain the K&N should be protected by an oiled foam pre-filter, so budget for one if you ride hard in sand or dirt.
Fitment is where buyers should slow down. The manufacturer lists this element for the 2010-2013 Polaris Ranger RZR 170, and it is designed to slide directly onto the OE air filter intake without any fitting or cutting required. Searches for K&N PL-1710 RZR 170 air filter, 2010-2013 Ranger RZR 170 high-flow filter, and reusable UTV airbox filter all point to this application. Install is a straightforward swap, and owners on user forums recommend a light coat of grease on the filter lip plus a firm, even airbox lid closure to keep unfiltered air from bypassing the element.
The manufacturer's listing names the 2010-2013 Ranger RZR 170. Other sources list later RZR 170 and RZR 170 EFI model years, so confirm your exact model year and airbox with the manufacturer before ordering.
According to the manufacturer, no fuel management modifications are required to obtain the increased performance this filter offers.
The filter is supplied pre-oiled. The manufacturer lists a re-oiling amount of 0.79 oz (23 ml) for future service.
Per the manufacturer, this element drops into the stock airbox using an application-specific sealing bead, so no modifications are needed. Remove the airbox lid, pull the old element, wipe out debris, and seat the K&N with the sealing bead facing the airbox. Owners on user forums suggest a light coat of grease on the filter opening and checking that the lid closes fully without forcing it. If you run an aftermarket airbox, one owner reports that a threaded center bolt used to secure the original filter can block the K&N from seating, so check your airbox before buying.
