OEM 1967 Pontiac Firebird GTO 400 closed element air cleaner. This part has been refinished to the original look of the 1967 cars featuring the California emissions requirements A.I.R. (Air Injection Reactance) for both the GTO and Firebird 400 models. The base features a very clean interior with short oval snorkel and is complemented with a new heavy duty air filter, new valve cover breather filter with clip, and reproduction GM licensed air cleaner service decal (1967 California specific). 

 A new reproduction chrome lid with new seal completes the assembly - augmented with a period correct wing nut. 
Note that the A.I.R. tube can be capped off if your engine doesn't feature the provision any longer. 

As an added value, a Pontiac 400-4 decal has been added (loosely installed) to augment the engine compartment.

This assembly presents well and remains an excellent choice to enhance your restoration. Best of all, it is a Genuine GM part!
