I don’t think any head porter ever wants to see numbers back up and it made me go back and try one more modification and picked up 3-4cfm from .350-.700 but not what I was hoping for. Once again this intake was never aimed by Mopar for a head flowing 305-310cfm so honestly I think it held its own. It’s a very quiet intake that would probably shine on a 280-290cfm head. The top of the runner is very thin and although there’s plenty of room to get that crazy 90 degree lip out and some shaping done it’s time to quit. He’s a couple pictures of before and after mods today. The after has the adapter on.
