The RAD Valve's seamless, one-piece, precision casting and continuous aeroform surfaces ensure maximum flow velocities and instant, explosive movement of air particles the moment you turn the throttle. 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.
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.
Each Boyesen RAD Valve is unique - tailor made to that model, year and displacement. While other aftermarket valves might change flange sizes or bolt patterns, they're basically generic - and require you to irreversibly cut your intake boot to install it! But with the RAD Valve, there are no compromises in power, no modifications."
