Boyesen RAD-42C RAD Valve Reed Valve Assembly

The Boyesen RAD-42C RAD Valve is an advanced aero-form reed valve system engineered to eliminate the performance limitations of conventional reed valve designs. This innovative valve maintains optimal flow velocity through the intake tract while redirecting the intake charge for even distribution across all intake ports.

Key Features:

• Aero-form design corrects airflow problems found in traditional reed valve systems
• Maintains consistent flow velocity and redirects intake charge for even port distribution
• Delivers quicker, sharper throttle response and increased horsepower
• 1-piece aluminum casting construction eliminates the need to trim manifolds or install plastic inserts
• Includes Boyesen Pro Series RAD Reeds for immediate installation

The RAD Valve's precision-cast aluminum body provides superior durability and performance consistency compared to multi-piece designs. By optimizing intake flow characteristics, this system helps your engine breathe more efficiently throughout the powerband, resulting in improved acceleration and overall power delivery.
