OEM 1961-64 Pontiac Bonneville Catalina 2+2 389/421 64 Pontiac GTO 389 Tripower Air Cleaner in good condition. This assembly has been media blasted and refinished to the original look of the 1961-64 cars featuring the infamous Tripower carburetion. The base features a clean interior with absolute minor interior anamolies, a straight filter ridge, smooth perimeter, and correct clearance dimples. The snorkels are straight and clocked at 10:30 and 12:30 - this defines the years it will fit correctly. Both snorkels are the same length. The internal carburetor mounting stancheons are original and mount to the three carburetors; note that the center carburetor flange is small, while the two outisde carburetor flanges are larger. The exterior has been updated with a GM licensed air cleaner service decal - correct for the 63-64 era assemblies, but looks at home on any year.

The original lid is included and in good condition - some minor impressions and curvature, but hard to see once installs. It sits nicely on a new air filter and is secured by a period correct wing nut.

This assembly is in good condition and remains an excellent choice to enhance your restoration. Best of all, it is a Genuine GM part!
