personally i wouldnt have spent the money on the AEM CAI. so u got lucky. i built my self one out of dryer tubing and a filter for 30 bucks(25 was the K&N cone filter) and it works as well as the AEM one. u could prolly use pvc piping as well. they're right when they say it dont do much for hp, almost nothing infact but it is loud and sounds great. the sound is worth the 30 bucks i spent on it.
ebay has generic short ram intakes

im assuming u have the V6 (3vz-fe), if im right , do a search for toysrme's threads on cheap/free mods. theres some excelent stuff that works really well on the 3vz.
edit: heres the link, it was almost impossible to find.
