Boyesen 531 Power Reeds

Boyesen engineers embarked on a mission to create a new lineage of aerodynamic intake technology by refining the primary performance factors required to increase peak horsepower through design innovation: aerodynamic surface optimization, model-specific reed petal tensioning, material fuel resistance, and multi-stage reed timing. Together, these innovations create a new technological benchmark in intake performance.
