For riders looking to unlock smoother airflow, sharper throttle response, and cleaner power delivery, the Boyesen Intake Manifold is one of the most effective upgrades available for two-stroke personal watercraft. Boyesen has spent decades perfecting intake flow technology, developing manifold designs that eliminate turbulence, improve fuel atomization, and stabilize airflow from low RPM through peak power. These manifolds help your engine breathe naturally and efficiently, reducing hesitation, increasing charge velocity, and supporting stronger overall performance whether you ride recreationally or competitively. A Boyesen Intake Manifold also pairs seamlessly with Boyesen reeds and Rad Valves, creating a full airflow system that maximizes the strengths of each component. The smooth bore transition, precision-machined surfaces, and reinforced construction give riders both durability and performance consistency under harsh riding conditions. At IPDRacing.com, we supply the complete lineup of Boyesen Products, including intake manifolds engineered for Yamaha, Kawasaki, and Sea-Doo two-stroke models.
