Description
Boyesen Racing Reeds represent a measurable upgrade for serious racers and high-performance builders who demand maximum intake efficiency. Laboratory flow analysis confirms that Boyesen’s dual-stage design delivers greater flow velocity across the entire operating range—from cold start through peak acceleration—translating directly to improved throttle response and power delivery. If you’re chasing every fraction of a horsepower, reed valve performance is non-negotiable.
