STI - OEM intercooler differences
 

Hi All,

I have a 2004 Forester STI & want to replace the WRX-sized OEM intercooler with one from an Impreza STI, along with a custom scoop duct. I'm a bit confused as to which is the best one to get/which variant will fit. Can anyone offer any advise?

I've found this style, advertised as v7/8 JDM:

Then there's this one, V7-9 but subtly different - 'flat' upper end tank:

Then this one, subtly different again:

Are the differences between model years/markets & interchangeability documented anywhere?
