The later versions of STI had red inlet manifolds

This doesn't have the red ones, as I know about the later versions having these fitted.
but this one has a fifth injector hole, and is a version 2.

On a 20 year old impreza with chocolate engine it's pot luck as to what it actually has in it.
The only real way of knowing is to pull it appart. But if it's working fine why bother
