This item is out of stock




OEM 1971-72 Oldsmobile 4-4-2 400/455 Dual Snorkel Air Cleaner. The assembly has been refinished in mid-gloss black 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 good condition and features a fully functional ThermAC pre-heater along with new white striped vacuum line. The smaller secondary snorkel is also fully functional and in good condition. The base is clean and comes with a correct 1971 air temperature sensor (ATS) installed with the correct retainer and both a new valve cover breather tube grommet. As an added value, the correct plug for the second valve cover breather assembly is included (used in lieu of the dual valve cover breathers).  The exterior features a reproduction Air Cleaner Service Decal (ND=71) 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 1971-72 cars due to the location of the dual filter breather outlets, 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 a period correct wing nut are included. To add further distinction, a GM licensed 4-4-2 decal is installed and complements the assembly. 

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