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 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 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. The custom chrome-colored cover give this air intake good looks while your bike is powering down the highway or at your local show.

K&N RK-3932 Intake System-Harley Davidson Product Reviews

Monday, August 27, 2018 - Part RK-3932
Had a bit of a fitment issue but eventually got it to work. Looks really nice and seems to work good so far.

Didn’t line up well with cylinder vent bolts had to play around with it too much and took some force to get it in. Disappointed in the fitment issue but I got it to work.
