GMC Terrain air intakes

Before buying my very own GMC Terrain, im looking into what mods I can do since I know i will catch the mod bug! Since air intakes are usually the cheapest mod you can do to a car I figured I would start with that.

what brands make GMC Terrain air intakes?
what brands do you recommend?
pricing?
best bang for buck?

Knowing that AEM, K&N & Injen are the top brands.... I would prefer one of those, but still list other brands please...

thanks!
