Description
A quality air filter is foundational to engine longevity and consistent performance—especially on high-demand quads like the TRX400EX and TRX400X. The Twin Air Pre-Oiled Air Filter delivers dual-stage foam filtration that captures fine dust and debris without restricting airflow, keeping your engine protected while maintaining the responsiveness you need in technical terrain. Since it arrives pre-oiled and ready to install, you’ll spend less time prepping and more time riding.
