as i said before all engines make this noise at some RPM just some are louder than others.if you took the air box off and reved the engine you would hear it on other cars too. the noise is most likely the air going through the throttle body. trust me as long as it is infact the air goign through the intake, which it definatly souds like that is the case here, there is nothing to worry about. although if any one feels the need to take thier car in to have a shop look at it by all means go aheand but they will prolly tell you the same thing.

I have a high pitch noise too when doing about 70-80 mph. The noise goes if I speed up or slow down, its just when maintaining speed.

well if there was no faults then theres your first sighn that it probablly isn't all that important to worry about. and they probablly told you they couldn't duplicate it becasue they didn't want to get into trying to fix a problem that can't really be fixed.
