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 beautiful chromed round custom cover gives this air intake classic elegance, perfect for the garage queen or road warrior alike.

I have K&N filters on everything I own, it is a great product! I will continue to use K&N on all my equipment, there is no better filter on the market to date. Thank you for a great product!

This intake system is great, easy to install and it looks great as well. But the biggest thing is the Power difference...definitely a power gain you can feel...I was skeptical...but now I'm a believer. And it actually made my Bike sound better. 2007 Electra Glide Ultra, 96CI, true Duals, Reinhardt Slip ons
