The Edelbrock Air Cleaner is designed to match the Elite Series valve covers and breathers. The Elite Series features a round air cleaner without the Edelbrock logo. It is designed to fit between the carburetor neck flange and the air filter assembly. The air cleaner removes dust from the air that passes through it. The Elite Series round air cleaner is 10 diameter and is made of aluminum with 2 filter element height. A black anodized wing knurled nut and PCV (Positive Crankcase Ventilation) valve adapter are included. To keep the engine clean, replace the original filter element in the Edelbrock air cleaner with a new element every 3,000 miles.
