Slant-Edge Air Cleaners are the perfect way to complete your dress-up look in premium Slant-Edge style. If you've got polished or chrome valve covers, these will set your engine bay OFF like no other air cleaner. The over-sized MOPAR emblem with MOPAR black inlaid paint is next level. They are supplied with genuine 3" GM air filter elements (GM P/N 6421746, AC Delco P/N A212CW) for maximum airflow. Each kit is supplied with necessary mounting hardware. Technical Note: After installing a new air cleaner, always lower the hood slowly to confirm sufficient clearance visually. Minimum clearance of 3-3/4" is required from the top of the carburetor gasket area to the underside of the hood. The air cleaner base is recessed for a low profile appearance. Patented Design.
