LS3 Intake on Cath Port Heads With Adapters! The LS3 intake is arguably the best factory GM intake ever made, but does it work with cath-rec port adapters used for LSA blower installs?

I wanted this to work so bad back in 2018 when I tested it, but it just didn’t pan out. Get a cath port intake! Make sure to check out the sales
