Hi Brad.
The car is Swedish, yes. I am sure the Cobb package will fit, and probablt work too on a Swedish car as its the same engine. Only question is the mapping. I think we have higher octane fuel here and maps may for that reason be different.
Also: There are tuners here in Sweden, and you should be able to find a package similar to the Cobb one. Not sure if they can match in price tho.
As I picked up my STI yesterday, I haven’t really spent any time searching for this. Quite ok with the stock power for now.
