OEM‑Style Air Filter – Polaris Scrambler 400 / Trail Blazer 400 / Xplorer 400 / Magnum 425 / Big Boss 500 (1995–2003) – Replaces 1253118 / PL‑1002 / 12‑94290

OVERVIEW

Direct replacement air filter engineered to maintain clean combustion airflow and protect engine components during routine maintenance cycles. This reusable foam air filter replaces factory elements on selected Polaris Scrambler, Xplorer, and Magnum ATV models. Constructed from high-density polyurethane foam media, it provides consistent particulate capture while matching original chamber dimensions for a secure drop-in installation.

ENGINEERING & PERFORMANCE

The compressed foam element restricts abrasive dust entry while preserving steady intake velocity across varying throttle positions. Designed to meet or exceed original engineering tolerances, the media retains its structural resilience under sustained heat and mechanical vibration typical of utility and trail operations. Model-specific geometry eliminates air bypass pathways, and the washable architecture allows repeated cleaning cycles without degrading filtration efficiency.

WHY RIDERS CHOOSE THIS

Riders choose this reusable foam air filter because it delivers dependable dust containment without starving older carbureted engines of necessary air volume. The resilient foam matrix flexes to seal tightly against stock housing ridges, preventing unfiltered particles from reaching sensitive cylinders while allowing unrestricted scavenging during hard acceleration. Regular washing restores the media’s breathability, which stabilizes throttle response and minimizes carbon buildup over time. Because the external contours align precisely with the factory mounting points, it eliminates guesswork and ensures reliable operation across mixed terrain applications.
