Hey guys,
Putting my head back together and I need help identifying what this port is, I believe the one next to it is a brake vacuum line and below it is a temperature sensor but this port right here looks like something was screwed into it.

This is from a MY06 S2000, Sorry for the iphone pictures.

 

It's hard for me to see exactly what your talking about but there are front and rear braces that bolt into the intake manifold. They are made out of thin black metal. Hope this helps

Edit: I just went and looked at mine for you and its the same way. Nothing is bolted into it and I have no modifications done. I wouldn't worry about it

 

Ah ok, thanks a lot. I was worried it was something important and I didn't install it or something.
