Filter Polaris RZR PRO R PRO R4 2022-2025

The Filter Polaris RZR PRO R PRO R4 2022-2025 by OTR FILTERS is a precision engine air filtration system engineered specifically for high-performance side-by-side off-road vehicles. As a mechanic familiar with RZR platform durability demands, I recognize this filter as essential maintenance for anyone running a PRO R or PRO R4 through dusty trails, desert terrain, or competitive riding environments. Proper air filtration directly impacts engine longevity, throttle response, and fuel economy—three factors that separate long-term reliability from premature wear.

OTR FILTERS manufactures this unit using multi-stage pleated media construction that captures fine particulate while maintaining optimal airflow under load. The design accounts for the Polaris RZR PRO R's aggressive intake airflow and the PRO R4's refined engine management system, both of which require filters that balance restriction-free performance with superior contamination trapping. At 2.48 lbs and measuring 8.7 x 8.65 x 12.3 inches, the filter achieves a compact footprint that integrates seamlessly into the stock intake assembly without requiring custom mounting or adapter brackets. Silicone seals and rigid frame construction ensure positive airbox sealing—critical to prevent unfiltered bypass that undermines engine protection.

This OTR replacement filter suits weekend warriors and competitive XC racers alike, particularly riders operating in high-dust conditions where stock filter change intervals compress dramatically. Installation requires no special tools—the 2022–2025 model years share consistent airbox geometry, making this a straightforward swap during routine maintenance. For those serious about engine protection and sustained power delivery, rotating this filter every 500–1000 miles (depending on conditions) prevents mid-range lean-out and keeps your PRO R or PRO R4 breathing cleanly at full throttle.
