Questins about a cai and other crap

[07FX2]

First time posting with this account. I'm 429 boss but can't access my account or yahoo so I just made a new one. Lol but to get to the point. I already done the gotts mod. But it don't feel any different. I read all about the open filters and how there really hot air intakes. But what about banks ram air? Is there any benefits to using it? I love the sound of the cais. So I kinda want one. But don't want a hot air intake. Lol. I already got a gryphon btw and I'm planning on buying ud pullys, e-fans, lt headers, full new exhaust si/so 3" and 4:10 gears. Plus the banks cai, with custom tunes if it really improves the power. How much more wl the 5.4 be after these mods aswell?
