- Offers maximum performance
- Made with Boyesen's patented dual stage fiberglass design for more airflow delivering more usable power than stock reeds
- Manufactured with Boyesen's exclusive DURA *FLEX material
- Your original one stage reed operates most effectively only within a narrow RPM range while Boyesen's one soft reed on top of one firm flow through reed gives you a wide range of intake control, plus increased intake velocity
- Minor change gives major H.P. improvements
- Top reed opens at lower RPMs allowing for more air and fuel flow giving you better throttle response
- Bottom reed opens at higher RPMs for maximum flow
- Faster opening and closing
- Greater low pressure (low throttle) response
- Greater velocity and flow area
- No engine damage if broken
- Longer overall life
- Matched to O.E.M specs
- More air velocity equals more overall power
