This vintage air filter is a high-performance part for the 1969 1970 Buick Riviera Rochester Quadrajet. It is made by General Motors and has a manufacturer part number of 7046246. The filter is designed to fit 4 barrel carbs and has a range of performance from 350 to 455 carbs. The air filter is perfect for those looking to upgrade their car's performance and breathe easy knowing that it is made in the United States. This item comes with no manufacturer warranty, but its vintage and high-performance aspects make it a must-have for any collector or car enthusiast. Selling as a core carb. I know nothing about it. Thanks.
