For reference, "her" car was/is a BMW Z4 convertible. She still found the induction noise in the Tahoe unbearable.
And I kinda agree with all that, having driven both vehicles a fair bit.
Honestly, the only way to deal with it is to hack the intake plastic and install a custom fabricated resonator box or side branch resonator. Which is probably what you removed to install that, correct?
Another thing to consider is this: Have you ever heard a front wheel bearing squeal in protest, or a flat front tire thump? So even if you seal the box against the hood, you are still going to hear it quite well in the cockpit. It will not appreciably reduce the noise you hear.
I agree , visit a salvage yard or two & purchase the stock parts .
