Description
A properly flowing air filter directly impacts engine efficiency and throttle response—two factors that separate a well-tuned bike from one that’s just coasting. The HIFLOFILTRO HFA4904 replaces your factory filter with premium Powerflow media that maintains optimal airflow without requiring carburetor adjustments or fabrication. If you’re running your Yamaha FJ1100 or FJ1200 hard, a quality filter upgrade is one of the easiest performance gains available.
