Problem is that there are a lot of cars out there now with one of these scoops on just for show.
So when you put them on a car that isn't a WRX, people think you're doing the same.
I'm looking at something for my air intake, as my turbo is a high mount on the back of the engine against the firewall. The intake has no fittings or air flow meters, etc, so I'm considering sticking a pod filter directly on the turbo inlet.
The only Toyota I've seen with a bolt on scoop was the 4A-GZE corolla.
Where did you get the photo of the WRX? Is it a bit wider to the left & been cropped? The wagon beside is a Caldina like mine.
