Permits adjustment of air/fuel ratio; not for pollution-controlled motorcycles
The air cleaner does more than house a filter. It needs to supply a large volume of clean air, and feed that air to the manifold rapidly, tumble it to prepare the air for the incoming fuel charge, all while managing engine breathing functions at the same time. For trusted performance, turn to Trask's Assault Charge.
This air cleaner looks great, works incredibly well, and recirculates the crankcase combustion vapors back into the throttle body like a stock Harley-Davidson air cleaner.
