Power Reeds & Pro Reeds by Boyesen
Boyesen’s patented dual-stage design incorporates a specially shaped top reed and a ported bottom reed. The top reed is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom reed is ported to provide maximum flow and horsepower at higher RPMs. More valves equals more power by creating More Air Flow, More Air Velocity, More Overall Power.

Rad Valves
Integrated into the seamless inner chamber are 4-way aerodynamic directional dividers that distribute the angled charge evenly without flow loss. Each channel has its own unique Power Profile, scientifically shaped to produce instant, explosive movements of air.
Intelligent Dual-Stage Reed System
Standard equipment on each RAD Valve, Boyesen dual-stage, Pro Series Reeds have the superior ability to time themselves to the needs of the engine. You get maximum flow velocity across the entire RPM range, and at all throttle settings. Smoth. Sharp. Smart.
A true, bolt-on Power Boost
There’s a Rad Valve Enginneered To YOUR Make, Year & Model. Each Boyesen RAD Valve is unique - tailor made to that model, year and displacement.
