Description
The stock air filter on your ST1100 is a compromise between cost and performance—and your engine knows it. The Hiflofiltro HFA1911 swaps that restriction for a high-flow design that improves throttle response and maintains clean air delivery without sacrificing filtration. Install it once, forget about it, and enjoy the breathing room your Honda deserves.
This is a direct bolt-on replacement that fits your factory airbox perfectly. No carburetor re-jetting, no custom fabrication, no guesswork. Hiflofiltro’s Powerflow media filters out contaminants while allowing significantly more air through than OEM, which translates to better combustion efficiency and noticeable mid-range punch.
