About K&N
K&N pioneered the washable, reusable cotton-gauze air filter and has been building intake products since 1969. On a V-twin, an intake swap is usually step one of the classic uncork — filter, exhaust, then tune.

This filter is crafted with pleated cotton-gauze media to deliver a significant increase in airflow to your engine while maintaining superior filtration.
