I ended up ordering the 450-304 intake.
I didn't realize they both used the same tube, but the other one had the insert and the this one doesn't. I guess that makes sense. I think the C&L intake does that too if I'm not mistaken.
I've got a tuner, and tunes for life from AM, so I don't need the insert. It saved me $20 to get the the -304 intake, so I'm happy. I don't know when I will receive it. I can't wait for it to get here though. It should be fun
