• Performance enhancing OEM replacement reed petals
• Patented dual-stage design incorporates a specially shaped top reed and ported bottom reed
• Top reed is lightweight and resilient for crisp throttle response at low-mid rpm's
• Stiffer bottom reed is ported to provide maximum flow and horsepower at higher rpm's
• The dual-stage design allows you to replace your stock reed stop with a Rev-Plate which permits the reeds to open freely and function efficiently
• The multi-port feature of the bottom reed creates more channels for the charge, delivering increased velocity to the intake ports
• Dual-stage reeds work in unison to perform efficiently throughout the entire powerband
• The difference in stiffness between the top reed and the bottom reed allow the reeds to respond quickly and accurately to changes in engine pressure
• Quicker acceleration, crisper throttle response and increased horsepower throughout the powerband
