Twin Air PowerFlow Kit 152215C Yamaha WR250F WR450F 03-15 Billet Cage Performance

Your Yamaha WR doesn’t just run — it breathes. Give it lungs worthy of a champ with the Twin Air PowerFlow Kit, built for WR250F (2003–2014) and WR450F (2003–2015). This isn’t some “good enough” stock filter setup — this is a high-flow, race-ready upgrade that replaces your restrictive backfire screen with a rigid, lightweight billet aluminum cage for a rock-solid, leak-proof seal.

That means zero dust sneaking in, more clean air flowing through, and your motor running crisp all day. Plus, Twin Air’s backfire-resistant foam laminated inside the filter adds extra protection without choking performance. More air, less restriction, better throttle snap — that’s the PowerFlow promise.

Installation? Easy. Maintenance? A breeze. Durability? The billet cage is built to outlast stock parts by years. Whether you’re carving tight singletrack or holding it pinned across the desert, this kit delivers consistent airflow and dependable filtration in even the nastiest riding conditions.

If you want your WR250F or WR450F to pull harder, respond quicker, and stay protected from grit and sand, this is the upgrade your bike’s been waiting for.

Fits Yamaha:
