K&N KA-6009R Race-Spec Air Filter for 2009-2023 Kawasaki ZX-6R / ZX636

Vehicle Fitment

• 2009-2012 Kawasaki ZX-6R (600 / 636 cc standard models)
• 2013-2023 Kawasaki ZX636 Ninja ZX-6R (all trims including ABS, 30th Anniversary, KRT Edition, and standard models)

Fitment Notes

• Racing-spec air filter - designed for closed-course or track use; stock engine settings may require fuel-management tuning after installation.
• Washable & reusable - must be cleaned, re-oiled, and inspected regularly to maintain performance and protection.

Features

• Two-ply cotton gauze "race" media - lower airflow restriction vs standard filters, optimized for maximum intake flow.
• Fewer pleats than standard replacement filters - further reduces airflow restriction for high-performance engines.
• High-flow design increases air intake for improved throttle response and potential power gain under performance riding conditions.
• Washable and reusable - long-term cost-effective choice compared to disposable filters.
• Panel-style air filter with OE-airbox drop-in fitment - no airbox modification required when fitment is correct.
• Pre-oiled and ready for installation out of box (in many kits) - simplifies installation for race or high-performance builds.
• Improved performance under high-RPM, track, or spirited-riding conditions where maximum airflow is critical.
• Durable cotton-gauze construction suitable for repeated clean/re-oil cycles over many seasons of use.

Product Description

The K&N KA-6009R is a race-spec, high-flow air filter engineered specifically for the Kawasaki ZX-6R / Kawasaki ZX636 Ninja ZX-6R (2009-2023) series. Built with a two-ply cotton gauze media and fewer pleats than standard filters, KA-6009R allows significantly higher airflow - ideal for track performance, aggressive riding, or any situation where maximum engine breathing is needed. Its panel-style design fits directly into the OEM airbox, requiring no modification when matched to correct model years and airbox configuration. Installed as part of a performance-focused build, this filter can help improve throttle response and support higher RPM airflow demands for more aggressive riding.

Because KA-6009R is designed for racing and high-performance use, proper maintenance is essential: the filter must be cleaned, re-oiled, and inspected regularly. Also note that using this filter may require fuel-management adjustments on stock or modified engines to maintain proper air-fuel balance. For riders and racers looking for a reusable, high-flow solution that supports aggressive riding and track conditions, KA-6009R is a top-tier upgrade that balances airflow, filtration, and longevity.
