I'm sure this may be a stupid question but i'm after a replacement MAF sensor my version 3 sti.
The question is what model of impreza's can i get a second hand MAF from? Does it need to be another version 3 sti or can it be from other versions or from wrx's? Is it a case where as long as it's a green label MAF it'll be the same?

 

V3/4 Impreza STi or Legacy GTB (BG5) or RSB (BD5) (manuals only).

 

Cheers

So wrx one's wont work? has to be sti?
