K&N Air Filter For Harley Dyna

K&N Air Filters are designed to achieve a virtually unrestricted air flow while maintaining filtration levels critical to engine life. The secret to their success lies in the unique characteristics of the filter medium initially developed by K&N all those years ago in the dust, sweat, and tears of desert motocross racing.

The high-flow cotton gauze air filter is washable, reusable, and built to last for the life of a motorcycle engine. K&N air filters consist of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance. K&N Air Filters were created for an environment requiring maximum horsepower and improved acceleration, and protection from dirt and dust. The result is an air filter that allows more air dramatically into an engine, is washable and reusable, and will protect your engine for its entire life.

This filter is designed to be a direct drop-in for your bike; no custom fabrication or non-stock components are necessary. Keep your stock airbox, but give your bike a bit more punch! As with any exhaust or intake modification, we recommend tuning your fuel delivery system appropriately, using a fuel controller, or re-jetting.
