Optimized air intake system provides superior efficiency, and acceleration for YOUR specific model machine, peak horsepower gains, tailor made to that model, year and displacement. Fit type: Vehicle Specific.

Integrated into the seamless interior chamber are 4-way aerodynamic directional dividers that distribute the angled charge evenly without flow loss. Increases peak horsepower through boyesens own innovations: Aerodynamic Surface Optimization, Material Fuel Resistance, Model-Specific Reed Petal Tensioning, and Multi-Stage Reed Timing.

The rad valve's seamless, one-piece, precision casting and continuous aero form surfaces ensure maximum flow velocities and instant, explosive movement of air particles the moment you turn the throttle.
