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. A scalloped drum-shaped custom cover gives this air intake the one-of-a-kind vibe that will make your bike a star.

K&N RK-3936 Intake System-Harley Davidson Product Reviews

Friday, November 2, 2018 - Part RK-3936
This air filter was installed in minutes. On my first ride after the installation I found I had more power in the pickup. It was well worth it. I will be looking at more filters for my other vehicles as a result. It’s a no brainer to change out the original air intake for a K&N air intake system.

Fits like a glove, and with the right tune it’s all value for the money.
