Boyesen RAD-42B Rad Valve

An aero-form reed valve that corrects the problems associated with existing reed valve designs. Maintains flow velocity through the valve and re-directs the intake charge for even distribution to the intake ports. Provides quicker, sharper throttle response and more horsepower. 1-piece aluminum casting; no manifolds to trim or plastic pieces to insert. Boyesen Pro Series RAD Reeds included.
