K&N universal air filters come in four styles – round straight, round tapered, oval straight and oval tapered
All K&N air filters in this section clamp directly to the carburetor throat, replacing the stock airbox and filter element; RC prefix part numbers have chrome end caps; the rest are black rubber (K&N clamp-on filters are not street legal)
Pleated design increases surface area air flow
Match the outer diameter (OD) of your carb throat with the inner diameter (ID) of the filter (given in inches and millimeters)
