OEM 1968 Oldsmobile 4-4-2 400/455 oval Air Cleaner. The assembly has been media blasted and refinished in gloss red 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 an original vacuum line (light overspray is apparent). 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. There is a very small indentation on the bottom of the snorkel - also out of sight once installed, but mentioned for clarity. 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 one indentation - 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 choice of one (1) GM licensed 4-4-2 decal or reproduction 455 Plate is included to complement the assembly. Please specify this in a note to seller; If no note is provided, the 4-4-2 decal will be provided.

As an extra bonus, the assembly comes with a two piece metal pre-heater set. The upper piece has a nice original rubber grommet that seals the unit to the bottom of the snorkel inlet; the lower piece slides onto the upper piece, then fits into the exhaust manifold flange of the stove/pre-heater shroud. Both pieces present and function very well.


This assembly is in nice condition and will enhance your restoration. Best of all, it is a genuine GM part! This is an original assembly with no apparent alterations.
