No for the love of God they won't. Don't just go buying sh!t because it's more expensive. If you feel that way just get a Mugen intake for $700+ or whatever.
Sometimes people just rip you off and you'll get the same results for much less money.
Personally I'd take any cheap ebay piping with a good pod filter over a full AEM/Simota/Injen intake because they're just too expensive.
EDIT: And you probably won't notice a huge power gain, maybe just a little better acceleration or it feels like it's rev'ing up more easily. Lots of noise too. Some of the big-brands claim to make an extra 4KW which is all very nice. But for sure you wouldn't be able to tell the power difference between a $100 CAI and a $400 CAI, provided you've used a good filter. For that use Fujita or 3A Racing like I said earlier.
