Boyesen 556 Power Reed Kit for Ski-Doo Snowmobiles

The Boyesen 556 Power Reed Kit is a high-performance replacement reed valve designed for Ski-Doo snowmobiles. Engineered to improve engine breathing efficiency, these reeds are a direct upgrade over stock components for riders seeking more throttle response and top-end power.

Key Features:

• Patented Dual-Stage Fiberglass Construction – The two-stage design allows the reed petals to flex progressively, improving low-end response while maximizing high-RPM airflow
• Increased Air Velocity – Optimized petal geometry promotes faster, more efficient air and fuel charge delivery into the combustion chamber
• More Airflow, More Power – Greater volumetric efficiency translates directly into improved throttle response and overall horsepower gains
• Direct OEM Replacement – Designed to fit into the factory reed cage without modification for straightforward installation
• Durable Fiberglass Material – Resists cracking and fatigue under extreme cold-weather and high-RPM conditions typical of snowmobile use

Boyesen has been a trusted name in performance reed valve technology for decades, and the 556 continues that tradition with a product purpose-built for Ski-Doo applications. Whether you ride trails or push your sled hard, upgrading to Boyesen Power Reeds is one of the most cost-effective performance modifications available.
