Love this car and want to take care of it!
I've been reading about problems with direct injected engines, not just Kia/Hyundai, because the fuel doesn't clean the back of the intake valves since it's directly injected into the cylinder, leading to carbon buildup on the intake valves and reduced efficiency.
CRC Intake Valve and Turbo Cleaner is recommended for this purpose in most threads I've read, and all state to spray it in after the air flow sensor.
Guys, I'm old school and might be able to hang with the middle of the pack on the pre-electronic engines, but where the hay is the best/proper place/way to do this on my engine?
