1970-72 Oldsmobile 4-4-2 W-30 Style Add-on 455 Outside Air Induction Air Cleaner & Top Assembly. This OAI is a nice reproduction of the original Olds outside air induction air cleaner assembly that completes the W-30 OAI option for the 4-4-2 with the 455 engine. The assembly is complete and functions correctly - as designed by Oldsmobile. The OAI top features a new vacuum actuator with vacuum line that works properly to operate the fresh air trap door; it has a minor repair on the bottom that is out of sight once installed, but mentioned for clarity. The OAI housing is nice and the 455-specific seal is new. A matching fresh-air air cleaner lid sits atop a new heavy duty air filter and completes the top assembly requirements.
The air cleaner base has been refinished in low-gloss black to present a period correct image. The large oval snorkel with the formed oval end (as opposed to smaller unit with pressed on end fitting) is in good condition with a functional ThermAC pre-heater along with new white striped vacuum lines. The base is clean and comes with a correct air temperature sensor (ATS) installed with the correct retainer. The exterior features a reproduction Air Cleaner Service Decal (NJ=OAI 71/72). 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 style and orientation of the snorkel. The base includes the second breather tube hole and drain holes in the bottom. A new air cleaner wing nut completes the package.
As an added value, a set of valve cover retainer clips/springs is included to make installation complete.
This assembly is in nice condition and will enhance your restoration. It is an ideal choice for adding an original W-30 Outside Air Induction (OIA) option to your 4-4-2 if your car didn't originally have it. Best of all, it is a genuine GM licensed restoration part!
