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. For buyers wishing a taller (4-1/32") filter, purchase GM P/N 8997189 (AC P/N A697C). The air cleaner bases are recessed for a low profile appearance, maximum performance and hood clearance. Patented.
