More Air Flow - 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.
More Air Velocity - The multi-port feature of the bottom
reed creates more channels for the charge, delivering increased
velocity to the intake ports.
More Overall Power - 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. This translates into quicker acceleration,
crisper throttle response and increased horsepower throughout the
