K&N custom air cleaner assemblies are designed for racing enthusiasts who demand both performance and aesthetics. These assemblies incorporate the superior airflow expected from K&N while maintaining a visually appealing design. Suitable for engines with round element air cleaner housings, these assemblies feature our renowned K&N Air Filters, offering increased airflow compared to other similar products. With four distinct designs available, there is a perfect 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 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 by facilitating smoother movement.
