OEM 1958 Chevrolet Impala 348 /1957 Pontiac Chieftain/Safari Tri-power Air Cleaner. This assembly has been media blasted and refinished in 60% gloss black to present a period correct image. The dual snorkels are in good condition and retain all of the factory spot weld marks where they were attached to the base, as well as those that attach the internal air inlets to the snorkel itself. The base is very clean and features the various indentations as stamped by the factory. The exterior presents the "C" stamped above each snorkel. The snorkels are clocked at 9:00 and 1:00 o'clock when looking from the rear, indicating this would be the early style of the assembly (PN 1553222). The orange over black A59C service decal completes the exterior to match the factory presentation as close as possible. 

The tri-power carburetor flanges feature the equidistanced flanges with tall stacks and small flanges - correct for the early style applications with factory original Rochester carburetors. This assembly is specific to 1957-58 cars due to the tall stacks and three wing nut starburst lid. Note later models changed the snorkel orientation  to 12:00 and 3:00 o'clock, more commonly seen and reproduced.

The original OEM starburst lid presents nicely and enhances the assembly. It features the correct triple wingnut wells and filter ridges. 

As an added bonus, an NOS OEM A59C square mesh air filter completes the package, along with period correct wing nuts.  


This assembly is nice and appears as originally produced -  it will enhance your restoration. Best of all, it is an utra-rare genuine GM part! 

Many of our parts are available only once - we cannot predict if/when another will become available due to the scarcity of original parts. The old adage "here today, gone tomorrow" applies to many of these unique assemblies. While we strive to maintain a strong diversity of desirable parts, there simply aren't enough available to meet demand at times. 

For further information on the restoration process and options, please contact us.
