Replacement Air Filter

The K&N HA-6414 is a high-flow replacement air filter engineered to enhance the performance of street-legal motorcycles. Its core is made from K&N's signature cotton filter media, designed to significantly increase airflow – by as much as 50% compared to OEM paper filters. This increased airflow is intended to translate into greater horsepower and torque, providing a noticeable boost to acceleration. Constructed to meet OEM size specifications, the HA-6414 is designed for a direct fit within the original air box, simplifying installation. The filter media is pleated to maximize filtration area, which contributes to high capacity and extended service intervals. Durability is further ensured by zinc-coated top plates, providing protection against corrosion. The filter comes pre-oiled and is ready for immediate installation and use right out of the box. K&N backs the HA-6414 with their Million Mile Limited Warranty, underscoring its long-lasting performance and reliability. As a washable and reusable component, it offers an eco-friendly and cost-effective alternative to disposable filters.
