OEM 1968 Oldsmobile 4-4-2 400 Oval Air Cleaner. The assembly has been media blasted and refinished in gloss red/orange to present a period correct image. The single snorkel with oval end (as opposed to smaller unit for 350 cars) is in good condition and features a fully functional ThermAC pre-heater along with new white striped vacuum lines (without factory overspray). The base is very clean and comes with a correct 1968 air temperature sensor (ATS) installed with the correct flat retainer.  The exterior features a GM licensed reproduction Air Cleaner Service Decal (OG=68) 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 1968 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; note that the rim features minor indentations - largely out of sight once installed, but mentioned for clarity. To complete the package, a new heavy duty air filter , along with a new breather filter and period correct wing nut are included. To add further distinction, a shelf-stock 4-4-2 decal is included (loosely installed) to complement the assembly. 

As an added value, the assembly comes with an original metal pre-heater. This upper piece has a nice original rubber grommet that seals the unit to the bottom of the snorkel inlet.


This assembly presents well and will enhance your restoration. Best of all, it is a genuine GM part!
