K&N Custom Round Air Filter Assembly 5-1/8in FLG / 9in OD x 4-1/8in HW/VENT 60-1120

K&N custom air cleaner assemblies are designed for racers who demand superior air flow and aesthetics. These assemblies are compatible with engines that utilize round element air cleaner housings and feature K&N's renowned air filters, offering increased airflow compared to other similar assemblies. Available in four distinct designs, there is an ideal assembly to suit various preferences. Each complete assembly includes a base, element, and top plate. K&N air filter assemblies utilize a surgical cotton fabric element impregnated with oil as their tack barrier. Sandwiched between layers of aluminum screen wire, the square holes in the cotton capture and straighten turbulent air, enhancing airflow due to the faster movement of air in a straight line. These assemblies incorporate an element and top and bottom plates, and are offered in multiple sizes and styles.
