K&N Air Filter HA-2511

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 the life of your ride.

KN Air Filter HA-2511 5 5 1 1
Best air filter and well worth the money I have used KN air filters on all my cars and never once have been disappointed. The air filters they make for motorcycles maintains that expected standard. Installation was easy (Except the sealer is kind of messy). Also, in the long run you save money going with this filter. This filter will outlast any OEM filter by far. [OEM filter cost about $30 and I would change it every 8 months to a year. The KN filter will last at least a few years (I've had KN filters last easily over 6 years), all you need to do is clean it off every 6 months to a year and you're ready to go] November 11, 2014
