Spark plugs are generally not the issue with Kia GDI engines, the problem is buildup on the port side of the intake valves not the combustion chamber side. This is due to there being no fuel flow across the intake valves and the oily mist that is routed back into the intake from the Positive crankcase ventilation system. You have three options to mitigate or fix this issue, have a cleaner run through the intake on a periodic basis while the car is also running, install a catch can inline into the PCV system, or just wait for it to impact drivability and take it into a Kia dealer and have them blast the intake valves with a walnut based blasting media. Not sure they are still using walnut based blasting media but if memory serves that is what they were using when I was working for Kia service. As you can probably tell the first two options are less expensive then the latter, so try to get those done to mitigate the issue rather than paying Kia to fix it later

My engine in kia sedona was cleaning by dry ice blasting is better than walnut blasting.
Checking the navigation history is a great tip
