Some early birds over here.

I think when people buy an aftermarket intake for a NA crossfire, they tend to lean towards the single cold air intake by NeedsWings. NeedsWings products are amazing quality, finish, and top notch performance gains. Prices are on the other hand are bit steep.

I'm not sure if the dual intake would be worth it on an NA if you only look at power gains. Would be best to do some research or wait for NA crossfire guy to chime in. They looking freaking awesome though!!
