The TRD intake arrived and fixed today. It is designed just like the stock oem intake except for being bigger with more airflow allowed.
I also deleted the sound-generator when fixing this intake. The delete kit was part of this cold air intake system.
Took the car for a test drive after installing it and my impression is as follow:
* It doesn't make power as the previous Injen intake used to at top-end. But, it surely has more torque and pull in low and midrange
* The part-throttle driving is much refined than both the Injen and the stock intake systems and this is due to the oem design of the kit
* The TRD CAI is makes a nice deep stockish sound and is not as ricey and loud as the Injen intake
* I'm very happy with my choice and I think it's money well-spent
