K&N Air Filter For Harley Twin Cam

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 which was originally 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 enhanced acceleration in addition to protection from the dirt and dust. The result is an air filter that allows dramatically more air 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 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, though the use of a fuel controller or re-jetting.

Economical Performance
Added this to my exhaust and fuel management upgrades allowing me to improve performance and keep the stock rain resistant air cleaner housing. Also this filter came with the K&N 1 million mile guarantee.

Big Improvement
I put this K&N filter on my 2010 Heritage Softail Classic. I saw an immediate increase in power and throttle response. I am very pleased with my order. I ordered the filter on Wednesday and got it on Friday. Thanks RevZilla!
