K&N presents its Street Metal Series High-Flow Air Intake Systems, designed specifically for Harley-Davidson motorcycles to enhance both appearance and performance. These systems boost engine power by replacing the restrictive stock OE air cleaner with a high-flow intake setup. Engineered with a robust, aluminum backing plate that directly attaches to the throttle body, it also features an integrated, internal-run breather system. Each system includes a K&N air filter, renowned for its high airflow capacity and extended service life, which is washable, reusable, and arrives pre-oiled for easy installation. A tough mounting gasket is provided within the kit to minimize vibration. With a blend of elegance and efficiency, K&N ensures these intakes not only look impressive but also contribute to a superior riding experience on the open road.
