UNI NU-8515ST Air Filter Polaris RZR 170

UNI High-Flow Foam Air Filter for Polaris RZR 170 (2010-2020)

Upgrade your Polaris RZR 170 with a UNI Two-Stage Foam Air Filter — engineered for maximum airflow, superior filtration, and improved performance in dusty environments.

Constructed from premium “Open Cell” Polyurethane Foam, this filter is designed to work with foam filter oil. The oil suspends within the foam like a web, trapping dirt particles effectively while allowing excellent airflow.

The filter features UNI’s signature Original Two-Stage Design:

• A coarse, thick outer layer captures large dirt and debris
• A soft, fine inner layer traps even the smallest particles

This dual-layer construction delivers outstanding protection while providing significantly higher airflow compared to stock paper filters. The result? Noticeable gains in horsepower and torque, along with a crisper throttle response and smoother overall ride.

Important Note: This air filter does not come pre-oiled. It must be properly oiled with UNI Foam Filter Oil (or equivalent) before first use.

Vehicle Fitment: Direct fit for all Polaris RZR 170 models from 2010 to 2020.

Perfect for riders who demand reliable filtration and better performance — whether you’re tearing up the dunes, trails, or just enjoying weekend adventures.
