I've had my intakes for about 3 weeks now, and since I got them I've noticed they make a short, deep "whistling" sound every time the transmission is about to change gears (upshift only). It almost sounds like a kid sucking through a big straw, and the sound only lasts for about half a second, but between each gear shift. I know you're supposed to hear a "shhhhhhh" sound as they suck air quickly, but is the whistle normal?
