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

It’s nice to hear that you’ve done your research. Most people don’t give it a second thought. I am familiar with the HKS filter but have never tried it as the foam element just doesn’t sit well with me. Let us know how it works for you. I was in the same situation with space as you are and asked K&N to build me a couple filters with a low profile and enough surface area and they did for pretty cheap. It was only a few bucks more than buying off the shelf so well worth it.
