Enhance airflow and performance for Harley-Davidson motorcycles with K&N design.

The K&N Street Metal Series High-Flow Air Cleaner Assembly is engineered to improve the performance of Harley-Davidson motorcycles by increasing airflow, horsepower, and torque. This assembly replaces the stock OE air cleaner with a complete high-flow system, featuring a durable aluminum backing plate that mounts directly to the throttle body. The integrated internal-run breather system ensures efficient operation while maintaining a sleek appearance.

Constructed from high-quality aluminum, this air cleaner assembly is designed for longevity and performance. The washable and reusable K&N air filter, made from red cotton gauze, comes pre-oiled and ready for installation, making maintenance straightforward. The versatile all-black aluminum cover allows customization to match the motorcycle's aesthetic, whether aiming for a rugged look or a more refined style.

Installation is user-friendly, with an estimated time of just half an hour, allowing riders to quickly enhance their motorcycle's performance. The K&N logo on the top design adds a touch of brand recognition, ensuring that quality is at the forefront of this product.
