DESCRIPTION

 

Ultra-rare OEM late 1957-58 Oldsmobile J2 371 3x2 Triple Carburation Air Cleaner. This assembly has been refinished in 60% gloss black to present a period correct image and features an Olds J2 Rocket Decal installed in the factory original location. The offset and differently sized snorkels with correct inserted oval ends are in excellent condition and specific to the Oldsmobile models.  This assembly is specific to late 57 and all 58 Triple Carburation models in that it was an update to the batwing oil bath models used early on in the program. Note that all of the carburetor flanges are the 2 3/4" diameter; later GM models introduced the larger center flange, as well as a myriad of differing snorkel locations and base plate indentations for the Cadillac/Pontiac/Chevrolet divisions. The overall paint is very nice; the interior has been cleaned and cleared to present the factory metal appearance with minor issues on the inside. The exterior is garnished with GM licensed J2 Rocket and correct A59C air filter service decal.

 

An OEM starburst lid features three wing nut holes and the FRONT callout. To complete the package, a  new high performance air filter and a trio of period correct wing nuts are included. Note that the early style Oldsmobile featured the starburst pattern with three holes to mount to the carburetors - the later versions reverted to single hole with a smooth lid. The inside of the lid has been cleaned and cleared - again, preserving the natural metal appearance while maintaining the original look.


While the intake manifold and carburetors were available in much larger numbers due to economies of scale within Olds (and other GM models for the carbs), the air cleaner was limited exclusively to the actual triple carburation models. As such, it is highly coveted and harder to find them- especially in good condition.


Original assemblies transcend both value and desire to collectors with classic car price points clearly demonstrating the difference.


This assembly is in nice condition and will enhance your restoration. Best of all, it is a very rare and genuine GM part!

APPLICATIONS

 

This assembly is correct for the following 1957-58 Rocket 371 / 300HP 3x2 engines with A/C:

Oldsmobile

Super 88, Super 98, Starfire Ninety-Eight, Golden Rocket 88, Holiday 88, Fiesta Wagon

 

This assembly is a one-year only piece due to the size and nature of the snorkels. The J2 option was released in 57 and extended sometime into 59 - purported total production of around 2,500 units. The earlier versions used a batwing oil bath filter, while later 57-59 models used the more conventional paper filter updated assembly. Note the carry-over of the 57 models into the early 58 run.
