Restoring American Muscle Car and Classics - we help your engine breath easier!
OEM 1977-79 Pontiac Trans Am Pontiac L78 400 Shaker Air Cleaner. The assembly has media blasted and refinished in semi-gloss black to present a period correct image. The base features the round snorkel in very good condition with the correct 4" opening, new yellow-striped and black vacuum lines, original ATS with clip, EVE valve, and a new heavy duty air filter. The exterior features a new GM Air Cleaner Service Decal (RD=77). 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. A date stamp has been added (rarely seen on these particular assemblies) as an added measure of authenticity.
The replacement shaker lid is very nice as well. To complete the package, a period correct wing nut and a new filter breather replete with rubber adapter are included.
This assembly is in nice condition and will enhance your restoration. Best of all, it is a genuine GM part!

This assembly is correct for the following 1977 models:
Trans Am with 400 L78 Pontiac engine & W-72 Option
*It will also fit 78 and 79 400s - the change of the air cleaner service decal would indicate which year.
Note: this will NOT fit the L80 403 Olds engines or Pontiac 301/Chevrolet 350 engines due to the offset of the shaker scoop, as well as the difference in carburetor flange drop.
The assembly will fit factory 4 barrel Quadrajet carburetors with a 5 1/8" diameter flange, as well as some Holley (it will NOT fit double pumpers; i.e. models 4150/4160), Carter/Edelbrock variations without an electric choke (some adjustment to the carburetor alignment tangs may be required). If you have modified your carburetor or intake manifold, please inquire first prior to bidding to ensure fitment is correct. Return requests for non-fitment will not be honored.
