OEM 1970-72 Oldsmobile 350 (455) oval Air Cleaner. The assembly has been refinished in gloss black to present a period correct image. The oval snorkel with the formed oval end (as opposed to smaller unit with pressed on end fitting) is in good condition with only a minor crease just forward of the base and features a fully functional ThermAC pre-heater along with new white striped vacuum lines. The base is very clean and comes with a correct air temperature sensor (ATS) installed with the correct retainer.  The exterior features a GM licensed reproduction Air Cleaner Service Decal (NG=70) that replaces the originally located decal.  As an added measure, an original date stamp has been recreated to add a nice touch of authenticity. This assembly is specific to 1970-72 350/455 cars due to the location of the filter breather outlet and snorkel.


An OEM lid enhances the assembly and features an original seal.To complete the package, a new heavy duty air filter, along with an original breather filter tube grommet, and period correct wing nut are included. To add further distinction, a GM licensed 350 Rocket decal is included (loosely installed) and complements the assembly. 

This assembly is in nice condition and will enhance your restoration. It could also be an excellent alternative for the Outside Air Induction (OIA) option (only missing the second breather tube inlet). 

Best of all, it is a genuine GM part!
