K&N Custom Air Filter Assembly - Round, Red - 5.125in ID x 14in OD x 3.87in H 60-1263

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, which deliver more air flow than other comparable assemblies. Available in four distinct designs, these assemblies cater to various preferences. Each complete assembly includes a base, element, and top plate. K&N air filter assemblies employ a surgical cotton fabric element impregnated with oil to act as a 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, which include an element, top, and bottom plates, are offered in multiple sizes and styles to accommodate different needs.
