Product Description

The K&N KA-2409XD is a high-flow, reusable and washable air filter engineered specifically for a range of dual-sport, trail, and motocross-style Kawasaki bikes - notably KLX250/S/SF (2009-2014), KLX250 (2018-2020), and the KLX300 series (2021-2024 including KLX300, KLX300R, KLX300SM). Its pleated cotton-gauze media and "XStream" dual-piece design deliver significantly increased intake airflow while retaining excellent dust filtration - ideal for off-road, trail, or mixed-use riders who demand both performance and engine protection. With a large filtration surface and high dirt-holding capacity, this filter allows extended service intervals under dusty or rugged conditions.

Installation is straightforward: KA-2409XD drops directly into the bike's OEM airbox using the specified base seal, without requiring any modifications, rejetting, or tuning when installed on stock engine setups. Because it's washable and reusable, it provides long-term value over disposable filters by reducing recurring replacement costs and environmental waste. For riders seeking improved throttle response, better engine breathing, and dependable filtration over many seasons - especially on trail, dual-sport, or motocross-style Kawasaki KLX bikes - KA-2409XD is a reliable, high-quality upgrade.
