This item is out of stock



OEM 1978-79 Pontiac Trans Am Pontiac W72 400/455 Shaker Air Cleaner. The assembly has media blasted and refinished in semi-gloss black to present a period correct image. The base features an oval snorkel in good condition with the correct 6" opening, new vacuum lines, and a new heavy duty air filter. Includes an original ATS with correct clip and new filter breather with GM Stamped adapter hose. The exterior features a new GM licensed Air Cleaner Service Decal (PU=78). The base features the correct deep drop required for proper shaker hood clearance, as well as the angled flange that parallels the base level with the sloped hood line. 

Please note that the rear of the air cleaner base has been previously clearanced - it was returned to as close as possible to original, however, it is not entirely round and there is a small rise on the floor. It will properly mount the shaker scoop using the shaker ring. This is mentioned for clarity so there is no misunderstanding. Almost all of the imperfections are out of sight once installed. 

The original shaker lid is in good condition as well with one small bend on the rim. 

To complete the package, a period correct wing nut is included. As an added bonus, the assembly comes with an original stainless steel shaker ring adapter with new square bolt and screw.

This assembly is in good condition. Best of all, it is a genuine GM part!
