Since the CAI won't be out for a while, I just installed a K & N Filtercharger air filter to help increase airflow for now. It gives a slightly louder sound (not as much as a true intake). Its about the same price as the TRD air filter.

K & N doesn't specifically have it for the tC yet, but it's the same filter as the Corolla/Matrix.

It was $45 at http://www.summitracing.com.

 

all you should need is a toyota mass air made for CAI'a and then mount it up to cai intake piping and theres your CAI till the real one comes out... i don't see why that wouldn't work since thats what there gonna be doin anyway.. just with the AEM name on it... i think
