brought 2014 kia soul for oil change and tire rotation and i feel like im being scammed.

I brought 2014 kia soul, with 57k miles, for oil an change and tire rotation and i feel like im being scammed. I got a txt saying the following things needed to be addressed immediately:
1) fuel induction service: 199.99$
2) brake flush: 149.95$
3) spark plug replacement: 304.11$

fair condition suggested:
1) cabin air filter: 89.95$
2) engine air filter: 69.95$

What do you all think? The repair rep at the dealership says he does not see my FUEL INDUCTION ever being done and its a priority it gets done.

When i asked him for a copy of the maintenance schedule he was referring to as it was his only copy. Lol really.

also anyone know if i do my own spark plug change with approved kia spark plugs and have receipt of the parts that this will not screw up my warranty on the car? Such a ridiculous easy job, why so exp?

thanks in advance
