OEM 1970 Buick GS Ram Air Air Cleaner Assembly in very nice condition. This assembly has been refinished to the original look of the 1970 cars featuring the four barrel Ram Air air cleaners. The base features a very clean interior, factory drain hole, correct Air Temperature Sensor, Dual snorkel inlets featuring new white-striped vacuum lines, GM licensed air cleaner service decal (BD=455), and a new breather filter. An original black lid augments the assembly, adding the factory look under the hood - there are minor anamolies in the lid - hard to see once installed, but mentioned for clarity. The assembly is completed by adding a heavy duty air filter and period correct wing nut.

The Ram Air adapter piece is in excellent condition as well. The bottom cups are complete and present very well. As an exceptionally nice value, a new embossed GS 455 decal has been added to the Ram Air adapter. To complement the entire assembly, an early production date code has been added. New foams are installed via the factory methodology, ensuring fresh air is channeled from the hood adapters in through the Ram Air assembly.

This assembly is in very nice condition and will enhance your restoration. Best of all, it is a genuine GM part!
