These four plugs are produced to Kia's specifications for fit, form, and function, so you get the same electrode gap, thread dimensions, and heat range the engine was built to use. Because they’re OE parts, they preserve factory tolerances and support long-term vehicle reliability when installed and gapped properly.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engines use Kia part 18843-10062?\u003c\/h3\u003e\n\u003cp\u003eThis OEM part fits specific Kia and compatible Hyundai applications that require NGK-manufactured spark plugs with the 18843-10062 designation.
