Definately Pontiac and or possibly Corvette .Its either one. Base fits afb and eldebrock carbs . too small for rochester quadra jet
If the louver count is right and the lid is heavy it is a Pontiac. It should have AC decals inside the lid. The base plate is heavier than any aftermarket piece too. I have one of these on my Old Roadster carb. The element is still available from WIX and others. Corvettes actually had sealed throwaway assemblies rather than the lid and baseplate setup like Pontiac had.
ive seen it before in pics. I want to say stude avanti. Dont quote me on that but I have one of those feelings that usually turns out to be right
Looks like the right height, louver count and shape - so I'd agree as stated earlier with 65-66 Pontiac 4bbl, A-Body cars and the early-mid 60s Corvettes, but not sure on the exact years. Also used on the Pontiac Sprint 6 Cammer in '66.
Ive had a few of those thin Louvered Air cleaners and got those from GTOs that were being converted to Drag cars.... the deeper versions were available from Cal Custom..
