Hiflofiltro Foam Air Filter for Yamaha WR250F 2003-2014 WR450F 2003-2015 HFF4014

A dirty air filter chokes your engine's breathing and bleeds horsepower—especially on trail and track bikes that see real abuse. The Hiflofiltro HFF4014 dual-layer foam design flows significantly more air than paper alternatives while trapping fine particles, giving you cleaner combustion and sharper throttle response. Better yet, it's washable and reusable, cutting your long-term maintenance costs without sacrificing filtration quality.

Precision engineering meets practical durability. This foam filter is engineered to handle the demanding conditions of off-road riding—dust, sand, mud—while maintaining consistent airflow lap after lap. Installation is straightforward: simply drop it in place of your OEM filter with no modifications needed.
