PRODUCT OVERVIEW
K&N Street Metal Air Intake Systems for Harley Davidson motorcycles replace the restrictive stock OE air cleaner with an oversized K&N High-Flow Air Filter and a high-volume cast aluminum housing. If you’re looking for an aggressive appearance but want a significant increase in airflow, resulting in more power, this high-flow air intake system is exactly what your Harley needs. Installation is so simple, it can usually be done in 90 minutes or less. The K&N air filter is washable, reusable, pre-oiled and ready for installation. This intake system features an updated, modern look with an oval-shaped matte black housing. Silver details and sanded fins further enhance the streamlined look. Internal breathers provide a sleek, clean appearance. This air intake has a classic styling with a savage appeal. These K&N air intakes are street legal in most states. They are not legal for use in California and other states adopting California emission standards.
