Does it look like it?

 

looks like one to me.

 

I don't have a H22A4 Intake Manifold to compare it too, but I have a few JDM H22A Intake Manifolds and it seems slightly different to me. I'm only looking at pictures of them though, as I don't have them right in from of me.. So I can say it's most likely not a JDM H22A, and definitely not a Euro-R. So it could only be a A1 or A4.

 

pull out the injector and see if your current injector clips will connect to it.
