Here is my take on seafoam. For cleaning injectors, not sure. As shipo said, most decent gas stations have plenty of additives that "should" do the same job.
Seafoam as an intake/cylinderhead/valve cleaner, different story. It does do a good job removing carbon deposits, which will hinder performance. The thing is, it won't do that if you put it in the tank. It has to be poured into the intake stream.
To this question, clean injectors do effect performance and fuel economy. If the injector is dirty, it can disturb the spray pattern leading to incomplete combustion due to a lean condition. The ECU then compensates by leaving the injectors open longer thinking that will solve the problem, and you then get a rich condition. The constant struggle generally leads to higher fuel consumption. More info here Troubleshooting and Cleaning Dirty Injectors
I will not say that seafoam will address this issue (nor am I saying it won't), but there is validity to it being a real problem.

- Combustion chamber deposits from modern unleaded gasoline are exceedingly minimal (and harmless) compared to fuels from a generation back, and very-VERY hard. Seafoam (and all other such treatments) is utterly incapable of removing even a portion of these deposits. If you were to say pull the heads off of an engine with say 200,000 miles on the clock and look at the deposits, or for that matter, to try and scrape some of them off you'd see what I mean.
- I've been wrenching on cars for over 40 years and never seen a "dirty fuel injector" as described. In modern OBD-II cars, such a condition would be identified and generate a CEL due to the rich condition.

Fuel isn't the only thing going into your engine besides clean air. The intake can gum up from crankcase blow by. Fords for example are famous for puking oil into the intake, clogging up vacuum passages and coating the back sides of valves with carbon deposits etc. Seafoam, applied correctly, can help solve some of that.
You make a good case though for the newest of vehicles however. I only drive old crap

I've reached 122 MPH on my car which is why I was wondering if H would be proper. Even though no one has given me a solid answer, I'd assume the car is DEFINITELY limited at 130 MPH, if it could even go that fast.

for oil change: add a couple of tablespoons down the oil filler opening. Run the car a couple of miles only and change the oil. Don't be surprise to see the oil color to be black as that is carbon being released. Let the oil completely drain. Oil may be a bit darker after the change. zNot to be concern. See hoe clean it will be at the next scheduled change. Do this maybe every 75,000 miles. Does a good job.

Obviously, I can't type, so let me try again without typos.

Whats this I'm hearing about intake manifolds cleaning and what not? Where else can I use Seafoam on the car? I was planning on using using it in the oil and dumping the rest into the gas tank but if I can use it elsewhere, I'm all ears.

I'm trying very hard not to reply in an equally-condescending way, but no, there aren't. It basically says just pour it into your gas tank.
