Description
The factory air filter in your FZ1 is a compromise between cost and performance. The Hiflofiltro HFA4911 upgrades you to a high-flow design using advanced Powerflow media that increases intake volume while maintaining effective filtration—no jetting changes required. You’ll notice sharper throttle response and more consistent power delivery, especially in aggressive riding conditions where airflow demands spike.
Installation is straightforward: this is a direct bolt-in replacement for your original airbox element. No modifications, no fabrication, no surprises. It’s the kind of upgrade that delivers real gains without complications.
