If they have the spoiler, it will. Contact them to see if they have the real spoiler. Your link is for a replica too.
I'm aware of the diferences between the USDM Civic and the Canadian CSX/JDM Civic. We do have a number of Canadian users on here though and I wouldn't doubt we will soon have CSX owners on here because of that.
Yet still, some people would prefer the real parts. Since I happened to find them the other day and then this thread, which is on a very closely related topic, popped up, I figured, "Why not?" and posted the link to help people out.
Anyway, many aftermarket replicas are made of inferior quality and material, so at least Mugen doesn't make their products out of fiberglass. Mugen does not sell simple body kits and their name is both well known and generally respected.
Boom Toys should carry many different items for many of the more popular generations of Hondas. If you don't see the product you are interested on their site, contact them and they may have what you are looking for.
The wing is a replica but its looks nice and you can paint it to what ever color you want.
I'm pretty sure Mugen products are capable of being painted too. And it's bound to look nicer. Makes you wonder why a company would post a photo of the products they are replicating, not the actual product they are selling.
