There you have it, TRD's new intake for the '07 Tundra 4.7L V-8. TRD claims that the assembly achieves an increase of 27-percent in airflow, all while still filtering just as well as the factory assembly. And more air means more power. Also, the TRD setup retains the California Air Resources Board's required hydrocarbon filter that appears in the factory filter system, so the TRD intake still captures polluting vapors that may escape when the vehicle is parked.
