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 ***emblies 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..
