So to verify the performance of every K&N cold air intake, we conduct before & after dyno tests of the vehicles each system was designed for. Plus, the heat resistant chrome finish blends with the look of any Harley Twin Cam 96 or Twin Cam 103.īut of course, talk is meaningless without the proof to back it up. The K&N 63-1131P AirCharger performance intake system takes care of this problem by opening up a direct airflow path to the cylinders. However, the iconic styling actually limits the volume of air that's able to enter the system, and that restricts the amount of horsepower and torque that your Harley Twin-Cam engine makes. To facilitate this, air is pumped to the cylinders through the intake system, which is located behind that chrome air cleaner cover on the side of your V-Twin engine. But the gasoline has to have oxygen in order to burn in that explosion. Once this power mix is ignited by the spark plugs, the resulting explosion pushes the piston downward, turning the crankshaft, and ultimately the back wheel. All you need to provide are basic hand tools and you can be down the road in an hour and a half or less.Įach Harley-Davidson spins that drive belt by filling its twin-cylinders with a combination of gasoline and air. The 63-1131P air intake kit includes everything you need to give your Harley extra power today. But it doesn't matter which H-D® model you ride, you can boost the horsepower and torque by simply adding a K&N 63-1131P AirCharger performance intake system. Lightweight pistons allow the engine to create power faster, while balance shafts help to offset vibrations on ridged mount applications like the Harley Softail. The latest generations 2008-2011 Harley-Davidson Twin Cam 96 V-Twin and the 2009-2015 Harley-Davidson Twin Cam 103 V-Twin contain numerous innovations that are designed to provide the low end torque that Harley's are known for. These legendary motors have seen many incarnations: Flathead, Knucklehead, Panhead, Shovelhead, Evolution, and Twin Cam 88. Thanks to the innovative design of the 63-1131P air intake, K&N guarantees that this kit will increase the power to the wheels of your H-D motorcycle.īig "hogs" have been owning the road since the first V-Twin engine was introduced in 1909.
