OEM 1972 Buick GS 455 Stage 1 Ram Air Air Cleaner Assembly. This assembly has been refinished to the original look of the 1972 cars featuring the four barrel Ram Air fresh air system. The base features a clean interior with drain hole, correct Air Temperature Sensor, Dual snorkel inlets featuring new white-striped vacuum lines, GM air cleaner service decal (BD=72), and a new breather filter. An original black lid augments the factory image, retaining the classic understated look. The assembly is completed with a heavy duty air filter and period correct wing nut. 

The 72 specific Ram Air adapter piece is in nice condition. All prior finishes were removed, then the parts were coated to resemble the factory gel-coat finish. The triangular and rectangular bottom cups are complete and intact. A Buick GS  455 decal is included on the Ram Air adapter, adding a nice touch of originality; an NOS GS 350 is available if requested. To complement the entire assembly, a reproduced date code has been added. New correct foams are installed via the factory methodology as well, ensuring fresh air is channeled from the hood adapters in through the Ram Air assembly.

As an added value, a Buick "Stage 1" decal is included (loosely installed) to further complement the engine compartment - especially for those lucky enough to have a V code Stage 1!

We will include the GS 455 decal unless you let us know you would prefer the GS350.

This assembly presents well and will enhance your restoration. Best of all, it is a rare and Genuine GM part!
