Wrx, Rs,Rx, STI all share the same chassis, yet are different in detail (think front & rear bars, bonnet, boot lid etc).

Catalogue doesn't tell you details..... you need to tell it via the vin what impreza variant to look for.

This is a sample of the data output by the system:

Fax :
Model Name :G10
Body Model :GC8HKED
Vin-Code :JF1GC8KDGYG049773
-------------------------------------------------------------------------------------------------------
Part Number Part Code Name Part Code Q'ty
-------------------------------------------------------------------------------------------------------
22794AA010 METER COMPLETE-AIR FLOW

16546AA020 ELEMENT-AIR CLEANER


Note the model name above: you'd expect 'GC8' but Subaru call it a 'G10'
