The new VForce4Ri utilizes a winged air guide that increases air velocity for a dramatic gain in throttle response. Paired with the new winged air guide is a custom intake manifold boot that offers a straighter shot to the intake that greatly enhances both airflow and performance. The VForce4Ri also incorporates carbon fiber reed petals designed to ensure superior reliability and maximum performance.

All “R” models include a rubber overmolded pad on the reed tip area of the reed cage to significantly improve reed petal life.
