I've heard it, still hear it ... it's more like a brief whine or whistle than a ring, right? I believe it is the intake. However, I've been wondering if it's actually part of the vacuum system. It happens to me when I accelerate, not necessarily even hard. Does anyone know if the vacuum system has anything to do with the fuel system, or performance in general? I haven't been feeling like my car performs like a 280hp car (even if it's only 230-240 at the wheels), and have been wondering if this sound has anything to do with that, especially if it is more than just the intake. I've asked two dealers to look at it/listen to it, but neither has found anything to fix with it. The loaner auto sedan I had this week felt faster than my 6MT coupe, and I know part of that is due to the way the power surges in the auto, but just getting to 60 or 70 MPH seems like it takes longer in my coupe even with good, crisp shifts. Anyone have any ideas? Anyone? Bueller?

This doesn't concern anything we are talking about here, but I notice your name is Gatlanta. I know someone from atlanta and believe it or not, I truly hate that person more than anythign in the world. For that reason, I kind of hate atlanta too and all of georgia. Yeah that sounds a bit extreme, childish, and crazy, but no one understands it except me. So........if you see anyone driving a red rsx over there, please break their windows and I will send you a check. Thanks for your help...
