DESCRIPTION

 

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 new and functions as designed by Oldsmobile. The OAI top features a vacuum actuator with new vacuum line that works properly to operate the fresh air trap door; it has a minor repair that is hard to see once installed, but mentioned for clarity.  The housing is nice and the 455 specific seal is new as well. A matching fresh-air air cleaner lid and new heavy duty air filter completes the top assembly requirements.

The original 4-4-2 air cleaner base has been refinished in low-gloss black to present a period correct image. The 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; it is not quite as wide as the 70 style snorkel. The base is clean and comes with a correct air temperature sensor (ATS) installed with the correct retainer.  The exterior features a GM licensed reproduction Air Cleaner Service Decal (NH=71/72) that sits where originally located.  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. A new air cleaner wing nut and heavy duty air filter completes the package.

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!
