1970 Duster AlterKtion, 4 Link, LS/T56/Turbo and Minitub

The filter is $120 filter that is widely used in the tuner world. I've done a TON of research on filters trying to find something that is acceptable. This one in the pics is the 30$ knockoff for mock up that would do what you say lol the actual filter is green unfortunately but is safe and should work well.
