Boyesen IM002 Billet Intake Manifold – Kawasaki 800 SXR Stand-Up
The IM002 is the undisputed king of intake manifolds for the legendary Kawasaki 800 SXR. Precision CNC-machined from marine-grade 6061-T6 billet aluminum and finished in durable black anodizing, this manifold dramatically increases plenum volume and smooths every internal airflow path to perfectly feed Boyesen’s patented dual-stage Power Reeds. The result is explosive low-to-mid punch that launches you out of the hole like never before, combined with a massive over-rev capability that keeps pulling hard all the way to the limiter in any conditions – surf, freestyle, or closed-course racing.
Unlike the restrictive factory cast manifold that creates turbulence and pressure drops, the IM002 eliminates bottlenecks and gives your 800 SXR the breathing capacity it was always capable of but never had from the factory. Freestyle riders instantly feel the bottom-end grunt that makes flips and submerges effortless, while racers love the huge mid-range torque surge that keeps them glued to the leader’s wake. Direct bolt-on installation means no hull or engine modifications are required – simply remove the stock manifold, install the IM002 with the included o-rings, and experience the transformation on your very next ride.
