1971-72 PONTIAC TRANS AM 400 455 DUAL SNORKEL SHAKER AIR CLEANER
OEM 1971-72 Pontiac Trans Am 400 455 Dual Snorkel Air Cleaner. This assembly has been refinished in semi-gloss black to present a period correct image. The base features the dual oval snorkels with ThermAC vacuum pods and pre-heaters in fully functional condition featuring typical factory stamping waves. It is exclusive to 1971-72 models due to the addition of the carburetor vent hole and is complete with a correct mint ATS, retainer, and new white-striped vacuum lines. The exterior comes complete with a GM air cleaner service decal (PQ-72). The base features the correct deep drop required for proper hood clearance, shaker tabs, as well as the angled flange that parallels the base level with the sloped hood line of the F-body. An original style date code has been added as a nice touch of authenticity.
The original shaker lid installs on top of the new heavy duty air filter and enhances the assembly. To complete the package, a period correct wing nut and a new filter breather replete with new insert and ribbed adapter are included.
A reproduction piece is displayed to contrast the significant differences in appearance, design, and completeness. Many vendors have stopped selling them due to the obvious differences.
These particular assemblies are seldom seen in any condition, making it a harder to find part. Note that the values of early 2nd gen F-bodies are rising substantially, making original cars much more desirable.
While not perfect, this assembly presents well and will enhance your restoration. Best of all, it is a rare genuine GM part!

This assembly is correct for the following 1971-72 models:
Firebird Trans Am 455
Note: while it is not technically correct, it will fit 70 cars as well, but features the carburetor vent tube hole provision as well as the second snorkel.
The assembly will fit factory 4 barrel Quadrajet carburetors with a 5 1/8" diameter flange, as well as 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).
Note: There are substantial differences between the flange/drop of the GTO/Grand Prix (A/B-body) air cleaner bases as compared to the F-body cars - hood clearance is the primary issue and the shallower A-body drop will not properly clear the sloped F-body hood line. The easiest visual means to identify is that the A/B-body assemblies have ribs on the center flange, whereas the F-body is of a smooth design. The carburetor flange drop is then far more obvious. Issues caused by using the wrong one are obvious on many shaker scoops - the back corners are broken due to hood interference.
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.
