If it did make it slower, then all the intake dynos would show it, but they all show some type of gain to be had. However, if you look at the intake, there is a box around so its enclosed to cool air when the hood is closed. Also, as cmkde mentioned, it should help at the higher boost levels with the JB4 since it'll allow more air to move through.
