K&N Crankcase Vent/ Breather Air Filter - Clamp-on, 1-3/4" I.D. Flange - 3" O.D - 2-1/2"H 62-1470

K&N crankcase vent filters are suitable for a variety of applications, including racing, vintage cars, and classic carbureted engines where owners want to improve the appearance of their engine.  The filters are available in multiple styles with universal mounting to fit a wide variety of valve covers. Constructed with a washable synthetic filter media, they can be reused multiple times.  Some styles also include shields for additional protection. The top plates and shields are chrome plated for durability and visual appeal, and some inlet tubes are zinc plated.  The filters come pre-oil and are ready to use. They can be driven with up to 1/4 inch of debris before airflow restriction necessitates cleaning.  However, legal restrictions apply in California, where the filters are only legal for racing vehicles that are never used or licensed for highway use. Consult knfilters.com for CARB status for specific vehicles.
