CLAMP-ON AIR FILTERS

• 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 carburettor 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)
• The pleated design increases surface area airflow
• Match the outer diameter (OD) of your carb throat with the inner diameter (ID) of the filter (given in inches and millimetres)
