Which Civic?

hey people

does anyone know what model US civic is the equivalent of the EU 03 Civic Vi here in Aus?

Will the parts from the US civics fit my civic?

I found an Injen CAI that I want to get for my civic but am unsure of if it will fit...do they have 1.7L civics there?

yes they do
they have EX HX LX & DX
and for hatch backs i think they have Si

do the parts from the US EP3 civics fit my EU civic?
