Product Description

The NGK 90909 (ILZKR8C8G) is a Laser Iridium spark plug engineered as an OE or OE-equivalent replacement for the 2.0L I4 engines found across a wide range of Hyundai and Kia platforms, including the Elantra, Kona, Veloster, Forte, Soul, and Seltos. The fine wire iridium center electrode delivers consistent, high-energy spark with low voltage demand, while the platinum ground electrode resists wear and maintains a stable gap throughout the plug's service life.

Note the unique specifications: a 12mm thread diameter and extended 26.5mm reach are specific to the Nu-family 2.0L Hyundai/Kia engine and are not interchangeable with standard 14mm plugs. The pre-set gap of 0.031 in and heat range 8 match the factory specification - do not re-gap unless instructed by the vehicle manufacturer. This plug replaces Hyundai/Kia OEM part 18867-09095. Sold individually; purchase 4 per vehicle.
