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.

I really liked product; but it worthless to me sitting on my shelf instead of the bike.
This is a great product but it doesn’t have the necessary over flow rubber hose to redirect that oil from the air-intake system. So it’s sitting on my shelf and not on my 2019 FLHTK....
