How to add seafoam through the vacuum line in a 2012 Ford Focus 2.0 L Duratec Ti-VCT I4 GDI?

I can find nothing for a modern Ford Focus all I find is ztech crap and focus from last gen. There seems to be no info really on the third generation to present focus. Where is the vacuum line that I would put seafoam in it was so much easier on my cobalt?

Hi so what do you expect it is a ford car. Seafoam does nothing to change the facts of life. Engine design does tho.

What is this National Sea Foam day?

What possibly makes you think you need to do that? You are in some fantasy land to imagine you need to do it.

I said screw it and put directly through the throttle body and problem solved. Car was a rental, then a lease, sold on auction, and at its final destination it sat a dealer for a bit of time. This was to the point where mice managed to ferry dog food into the intake silencer so I'm sure this car sat stagnant for some time as this was a Chevy dealership.
