Boyesen RAD52B-2 RAD Valve Intake System for Arctic Cat

The Boyesen RAD52B-2 RAD Valve is a high-performance intake system designed specifically for Arctic Cat two-stroke snowmobiles. This precision-engineered component replaces the stock reed valve assembly to optimize airflow and deliver measurable power gains throughout the RPM range.

Key Features:

• One-piece cast aluminum construction for superior durability and resistance to failure compared to plastic or rubber components
• Aerodynamically optimized internal surfaces with 4-way directional dividers that evenly distribute intake charge without flow loss
• Dual-stage carbon fiber reed petals for crisp throttle response and extended service life
• Model-specific design ensures proper fitment with no modifications required
• Seamless interior chamber design maximizes flow velocities for instant, explosive air movement
• True bolt-on installation with no cutting or permanent modifications to intake boots

The RAD Valve system provides improved throttle response, enhanced acceleration, and horsepower gains that arrive sooner and carry longer through the power band. The precision casting and continuous aeroform surfaces ensure your engine receives maximum airflow at velocities exceeding 500 MPH, allowing it to take over 200 gulps of air per second without restriction.
