Product Description
Upgrade your 1999-2007 Suzuki GSX1300R Hayabusa’s breathing with the K&N SU‑1399 High‑Flow Air Filter. Designed specifically for the Hayabusa’s airbox, this filter replaces the stock element while delivering improved air flow, which can translate to better throttle response and increased horsepower and torque. The multi-layer cotton gauze media offers superior filtration and a larger surface area than stock filters, allowing longer intervals between cleanings without sacrificing engine protection.
The SU‑1399 installs directly into the OEM airbox — no modifications or fuel system adjustments are needed. It’s washable, reusable, and built to last: simply clean and re‑oil as needed to maintain optimum performance. This makes it an excellent choice for riders who want a performance upgrade and long-term value without frequent replacement intervals. Ideal for sportbike enthusiasts who demand reliable power, smooth throttle response, and low maintenance.
