TRD Cold Air Intake

where did you get this intake from and how much does it cost? Is it better then say k&n or air raid?

Would you say its worth it from stock intake? and how different was the change?

I like the louder intake and exhaust sound the intake gives. I wouldn't say that you can "feel" the power increase, but it does show up on the dyno. No more buying disposable filters is a plus too.
