The engine of your Harley Davidson can produce power only if the fuel is mixed with enough oxidizer to be ignited in the combustion chamber by spark plugs at the right moment. Gasoline cannot burn without oxygen, which is why it needs to be delivered to the engine with fresh air. But before the flow can be drawn into the engine, it must be filtered to remove all contaminants that can clog up the injectors, carburetor, valves, and so on. The oncoming stream may include sand, dust, insects, and other debris which are harmful to some components of your motor, including MAF sensors, butterfly valves, and so on.
Air filters are designed to sift out even the finest dirt particles from the intake flow thus allowing the motor to “breathe easily.” In our online store, you can find a huge variety of air filters that use pleated synthetic and cotton media thus offering clean, unrestricted flow. Such components can improve your bike’s gas economy and performance while ensuring excellent air cleaning, longer maintenance intervals, and overall service life. Check our collection of Harley Davidson motorcycle air filters by such companies as Arlen Ness, Hard Drive, Breathless Racing, and so on.
