Another reason ive been told of that is an issue with bonnet scoops on n/a cars is only when a hole is cut in the bonnet underneath an aftermarket scoop, which alters the structure and compromises the strength of the standard bonnet.

From what i understand, cars with factory scoops have their bonnets reinforced around the hole, therefore a factory wrx bonnet shouldnt be an issue there.. Though the whole sealing of the scoop could well be a problem, im not sure at all. Ive had a fmic for years now, and had many police look under my bonnet, but the fact that theres no top mount to complete the seal has never been mentioned to me.
