could u give a better discription, like describing the sound and not using "like an airplane" cause that makes me think, 747, 767, C172? Hissing can be a vacuum leak, tapping can be an exhaust leak, how's the car performing?

Ported vac leak, alternator whine, or you're hearing the air going past your throttle blade. Try to discern whether the sound is related to engine rpm or throttle position.

Did you put a cold-air intake on? You might just be hearing the filter, that's all.

The MPFI V6's make a loud "whistle" draw through the throttlebody with the stock air snorkels off of them. That is normal.

i think its more throttle related, only happens when i rev her up, i think it could be the air passing the throttle blade like you said, i have a video i just need someone to upload it unless you want me to send it to you guys,
