Description

K&N street metal air intake systems for Harley Davidson Dyna, Softail, touring and Twin-Cam RK-3955 motorcycles increase power by eliminating the restrictive stock OE air cleaner and replacing it with an oversized K&N high-flow air filter and a cast aluminum high-volume aluminum housing. K&N high-flow intake systems give your Harley an aggressive appearance while providing a significant increase in airflow resulting in more power.

Key Features

GUARANTEED INCREASE IN HORSEPOWER & TORQUE: K&N cold air intake systems provide a less restrictive path for airflow, increasing the volume of cool, oxygen-rich air into your engine.

DYNO TESTING YOU CAN TRUST: K&N air intake horsepower/torque testing is performed on wheel-based dynamometers and the reports are included with each intake system.

IMPROVED ENGINE SOUND - HEAR THE GROWL: K&N’s intake systems allow your engine to breathe and sound as it should- your engine will growl on acceleration and return to quiet once at speed.

BETTER TOWING: K&N Air intake kit improves acceleration and uphill performance when towing by improving throttle response, overall horsepower and torque. Excellent for daily and highway driving.

PREMIUM ENGINE PROTECTION FROM A TRUSTED BRAND: K&N air intake will not void manufacturer vehicle warranty & No-Hassle Lifetime Limited Warranty protects for the life of your vehicle.

HIGH-FLOW REUSABLE AIR FILTER: 4 layers of pleated, breathable cotton with K&N’s red filter oil to absorb dirt & dust particles, allowing clean air to continue flowing into your engine, only needs cleaning every 100k miles under normal highway conditions.

EASY TO INSTALL: Includes detailed, step-by-step instructions & all necessary parts- the entire air intake system can typically be installed in less than 60 minutes with basic hand tools.

MADE IN THE USA: Proudly made in the USA for trusted quality & reliability and backed by US based customer support.
