OEM 1969 Oldsmobile 4-4-2 400 (455) oval Air Cleaner. The assembly has been refinished in gloss red to present a period correct image. The large single snorkel with the formed oval end (as opposed to smaller unit for 350 cars with pressed on end fitting) is in very good condition and features a fully functional ThermAC pre-heater along with new white striped vacuum line ( without the factory overspray). The base is very clean and comes with a correct 1969 air temperature sensor (ATS) installed with the correct retainer.  The exterior features a GM licensed reproduction Air Cleaner Service Decal (OS=69) that replaces the originally located silk screen.  As an added measure, an original date stamp has been recreated to add a nice touch of authenticity. This assembly is specific to 1969 cars due to the location of the filter breather outlet, snorkel size/orientation, and pre-heater inlet location on the bottom of the 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 and period correct wing nut are included. To add further distinction, a GM licensed 4-4-2 decal is included (loosely installed) and complements the assembly. 

This assembly is in nice condition and will enhance your restoration. It will also be an excellent base for the Outside Air Induction (OIA) option. Best of all, it is a genuine GM part!
