I have mixed feelings about this. with DI, there is nothing cleaning the backs of your intake valves from PCV gases and whatnot. the prices quoted sound unrealistically low to be honest. If the engine works fine, maybe don't bother with that service, but if you feel hesitation that wasnt there before, do it. my 2014 had 150k before it wrecked, and I felt it stutter a bit at low throttle sometimes where I would have to rev it higher before letting off the clutch or else it MIGHT stall when going from reverse into 1st. if you did coolant at 55k, you should be done. I'd recommend maybe spark plugs after 8 years but that's just prudence.
