K&N 2001-2006 Honda CBR600F/CBR600F4i Replacement Air Filter

Upgrade your 2001–2006 Honda CBR600F / CBR600F4i with a high-flow K&N air filter. Boost horsepower, sharpen throttle response, and enjoy reusable lifetime durability.

Unlock the full performance potential of your middleweight sportbike with the K&N High-Flow Replacement Air Filter engineered specifically for the 2001–2006 Honda CBR600F and CBR600F4i.

Designed as a direct drop-in replacement for your factory paper air filter, this premium upgrade increases airflow by up to 50%, feeding your fuel-injected engine the air it needs to generate crisper throttle response and noticeable horsepower gains across the RPM range.

Unlike disposable OEM filters that restrict airflow as they trap dirt, K&N filters utilize multiple layers of oiled, woven cotton gauze sandwiched between pleated aluminum wire mesh. This state-of-the-art filtration media captures microscopic harmful contaminants while maintaining exceptional air velocity.

Engineered to last the entire lifespan of your motorcycle, this washable and reusable filter is pre-oiled and ready to install directly into your factory air box without requiring fuel re-jetting or custom ECU tuning under standard riding conditions.

4. Washable & Reusable: Easily cleaned and re-oiled using a K&N Recharger Service Kit, restoring the filter to like-new condition time after time.
