1965 L37 396/425 or 375HP Z-16 1966 427/425HP L72 Dual Snorkel Air Cleaner. This is an original (OEM) assembly that has been refinished to a period correct image. The assembly features the original flat bottom base with the correct dual snorkels that are attached without the revised flanges or base groove as was the 1970 and later Z-28 LT1 assemblies. Both snorkel inlets are very nice with minimal distortion (very minor impressions on top of driver's side), as are the original interior flanges that they were welded to by the factory. A nice dimpled spark arrestor screen sits perched on top of the original flame arrestor tube and has a GM stamped rubber adapter fitting. The exterior features a choice of the correct PN GM licensed reproduction air cleaner service decals: as removed - PN 6421214 (65 396/375) or PN 6421970 (66 427/425). Note that the base features factory stamping patterns that remain in place as found.

A reproduction triple-plated chrome lid or OEM black lid enhances the assembly and comes with a new seal. The chrome lid is garnished with an original 396 die-cast emblem replete with mounting studs and speed nuts and a choice of 375 or 425 HP Turbo-Jet Decals, or a GM licensed set of  427/425HP Turbo-Jet Decals (please select your choice with a note to us). Note that original Z16 air cleaner lids came with a die-cast emblem - reproductions are available as well for those wishing to have the perfected appearance. 

The assembly is completed with a new heavy duty air filter and period correct wing nut.

This is an extremely rare assembly that was made available on a very limited number of cars. 1965 models featured the chrome lid, while 1966 cars featured a black lid. A photo collage provides comparisons to an original 1970 Z28 air cleaner, illustrating the originality of all the components. Some additional points of clarification for the early style dual snorkel:

  • Flat bottom base (later Z-28 models were ridged)
  • Snorkels mount to flanges extending from the base (later Z-28 models used flanged snorkels)
  • Limited indentations on rear points clearance area at rear of base (later Z-28 models featured additional wrinkles)

Pictures of the air cleaner were taken in its original state to validate the emblem, snorkels, and decal locations for aid in returning the assembly back to a period correct image. We welcome any questions regarding this air cleaner that you may have.
