After I made my intake from a very helpful thread, I hear a scratchy sound coming from the intake. It stops after like harder throttle or 15mph but upon startup and idle it makes this scratchy, rusty sound. Did I do somethin wrong or is the filter maybe messed up from the factory(its brand new) and its pretty embarasing qhen u start it prole prolly think its A pos. P.s. It never made this sound before. And it almost sounds like my air conditioner did when the clutch was going
