The Pro-Charge strip will let you know when it's time to clean your filter. Each filter is washable and reusable. Use Edelbrock Pro-Charge(TM) Cleaning Kit #43600 to clean and re-oil. The Pro-Flo Universal Fit Conical Series features triple chrome plated trim for a show-quality look. They are also designed with three inlet adapter rings for use on 3, 3. 5 and 4 inlet tube systems.
