The BOYESEN Rad Valve & Carbon Reed System is engineered with one‑piece aluminum castings and integrated bolts, allowing a seamless installation without the need for additional modifications. Its design maintains flow velocity through the valve while redirecting the intake charge to achieve a more even distribution across the intake ports, ensuring consistent airflow to the combustion chambers.
Performance is enhanced through a specially‑designed reed cage that securely houses Boyesen’s patented dual‑stage reeds. The hot RAD valve delivers a quicker, sharper throttle response and increases horsepower throughout the rpm range, while also providing substantial torque for improved drivability.
