Autozone or pepboys has all the adaptors etc need to do a custom SRI or CAI.
Ultra Racing might make one for our car, but the most common is TRD. I am a TRD freak, and i just stayed with the stock strut bar, it really doesn't make a difference between the two... i do alot of tracking too.
If you want to make a difference get the rear swaybar done.
Ignore the dirt this was taken in the middle of winter... i kept the airscoop on the car so it blows cold air tothe filter.

I am switching to a K&N cone filter though.
