BOYESEN engineers create a new lineage of aerodynamic intake technology to increase peak horsepower through design innovation: Aerodynamic Surface Optimization, Model-Specific Reed Petal Tensioning, Material Fuel Resistance, and Multi-Stage Reed Timing. Together, these innovations create a new technological benchmark in intake performance.
Each Boyesen RAD Valve is unique - tailor made to that model, year and displacement.
- 100% Aluminium body with aerodynamic internal surfacing
- 4-way aerodynamic directional dividers that distribute the angled charge evenly without flow loss
- Carb boot clamp and gasket provided. No modifications required.
- Model-Specific variable tension reed petals (Aerospace carbon material)
- Rubber coated and fuel resistant reed petals to ensure a long-lasting seal
Race proven RC2 series Rad Valve results in an optimized air intake system that provides superior efficiency, peak horsepower gains, and acceleration for YOUR specific model machine
