Yep you sure will hear it. It won't be as load as an atmospheric bov, but you'll hear it. Some go for Jetex. I personally went for "Green" and bought a cylinder filter. My advice is go as big as you can but stay away from foam. if you go onto Greens website the filters are shown as a diagram with the 3 dimensions of size. When you fit it, arrest it in place with anything you can cos MAF sensors are very sensitive to movement. Your car will sound miles better with a cone or cylinder filter. Well worth 10mins effort. I'm happy with mine.
Oh, don't over oil the filter either. no oil is better than too much.
