One of the first modifications that motorcyclists make is the addition of an aftermarket air cleaner or filter element. Since 1969, K&N has been perfecting the process of filtering the air that goes into motorcycle engines. Now, K&N has released a new product that not only provides clean air for your Harley-Davidson engine to breathe, but looks great while doing it. K&N claims that the new system adds up to six horsepower. Not bad for a simple bolt-on kit.

The new systems from K&N are the 63-1134 and 63-1137 Aircharger intake systems. The 63-1134 fits 2008-2016 Harley Touring models, while the 63-1137 bolts onto 2001-2015 Harley Dyna and Softail models. Both kits include a cast aluminum intake tube and come in a textured black finish with a raised, brushed aluminum K&N logo. This styling exudes performance, while also providing a timeless design that would look good on any style of bike build. The kits feature an oversized, oiled cotton, clamp-on air filter that feeds air directly into a wide air tube with an integrated velocity stack. An integrated breather system ensures these kits are a direct replacement for your stock intake.

Guaranteeing power is something that K&N is known for and these kits are no different. K&N dyno tests produced an estimated 6 horsepower and 6.5 lb-ft of torque gain for the 63-1134 kit on a 2016 H-D Street Glide. The 63-1137 system made an estimated 5 horsepower and 8 lb-ft of torque on a 2016 Harley Switchback. These power numbers are achieved using technology that K&N pioneered on their car and truck intake systems. Now, using cast aluminum, K&N is able to precisely direct the airflow to limit restrictions and promote smooth, laminar flow and increase airflow velocity.

These kits will be unveiled at the Sturgis Motorcycle Rally, so if you will be in town, swing by the K&N booth. It will be located in the vendor area at Black Hills Harley Davidson. For more information on this kit or any others, visit www.knfilters.com.
