Why Choose K&N for your Gen 1 Hayabusa?

The Gen 1 Hayabusa remains an icon of engineering. Because its performance is heavily reliant on its high-velocity intake system, a dirty or restrictive paper filter can noticeably dull throttle response. The SU-1399 ensures that the intake path remains low-restriction, allowing the engine to pull harder through the mid-range and providing that signature intake roar that Busa owners love.
