Boyesen

Rad Valve Blocks

Maximum Power achieved through air intake, acceleration and distribution. 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. Result: A true, bolt-on Power Boost. 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. Smooth. Sharp. Smart. Result: Full Spectrum power and throttle response.
