Based on the data we see here and the various types of intakes tested, I don't see how that could be possible.

any opinion as to which had the best performance, and least noise at high rpm? on my other truck the closed box intakes tend to make so much noise,
With past experience taken into consideration, the CAI, Inc intake performed the best at high RPM (> 5600rpm). Noise levels were not observed.
