K&N’s Street Metal Series High-Flow Air Intake Systems provide attractive styling, offer increased airflow and deliver more horsepower & torque to your Harley-Davidson motorcycle. These air intake systems eliminate the stock OE air cleaner and replace it with a complete high-flow air intake system to increase power. The sturdy, custom aluminum backing plate mounts directly to the throttle body via an aluminum integrated, internal-run breather system. The air intake system comes with a K&N Air Filter for high air flow and long service intervals. The K&N air filter is washable, reusable, pre-oiled and ready for installation. To help absorb vibration, a durable mounting gasket is also included. An elegant chromed custom cover makes this air intake a showstopper; your bike is sure to be turning heads with this one.

Great product. Easy to install. Worked great with my new (Brand Name) pipes. Definitely noticed an improvement even before I put the pipes on. Looks great as well. I will recommend the RK-3934 to anyone looking to upgrade.

The RK-3934 arrived with a small but deep scratch on the chrome face plate & I wasn't impressed. However I decided to install it as I had been waiting to get it on the bike & did not want to waste more time returning it as damaged stock. That's the only sorry part. The build & quality is supperb. & my 2013 softtail is a much happier bike. A great product guys I hope K&N stick with making strong durable products. 'm happy to pay for quality & trouble free products.IM VERY HAPPY.
