Just buying the cheap one and drilling a couple of carefully located holes through the FRP would be a budget solution.
Probably at track and motorway speeds in wet conditions where momentum is pushing the air through the scoop in addition to the 'suck'. The inside of the RB scoop is laminated and slick too... unless the inside arrives scratched to hell like mine was. You'll have seen how rainwater glides up and over bodywork at high speed. Add suction to that effect. You can hear the scoop making a 'whoosh' noise. It's hilarious and makes the car sound like a vacuum cleaner. Definitely don't buy a scoop for the sound.
I've put a gap between my scoop and air box to act as an extra rain gutter. Means that I lose/disturb some air but I was nervous about water ingress (particularly as I drive it in all weather) and was curious whether it would hamper performance much. I'm data logging to see if the modification makes a notable difference and have a few more things to experiment with.
The only time I notice difference after addint something was the cataclean
