The High Efficiency Air Filter for road & race bikes is designed for inlet noise reduction.
The revolutionary High efficiency Airfilter is designed to reduce intake noise and yet deliver more power. This design of airfilter has shown a reduction of up to 8db of intake noise compared to other sportsfilters.
Unlike all other sportsfilter, all inlets with this High Efficiency Air Filter will get the same quantity of air, regardless the speed of the motorcycle or wind directions. No different fuel-mappings between internal & external or front & rear cylinders are needed, this will be achieved by tuning each cylinder separate.
