Product Description

The K&N HA-6001 High-Flow Air Filter is a direct-fit replacement for the stock air filter used in 2001-2006 Honda CBR600F4i and CBR600F models. Its pleated cotton-gauze media and generous filtration surface allow the engine to draw in more clean air with lower restriction, improving throttle response, engine breathing, and overall performance compared to standard paper filters.

Installation is simple: the filter drops into the OEM airbox using stock mounting points and seals with an application-specific bead for a secure, airtight fit. Because it is washable and reusable, the HA-6001 offers long-term value by reducing the frequency and cost of replacements - making it an ideal upgrade for riders seeking enhanced airflow, better engine efficiency, and long-lasting filtration performance from a single air filter swap.
