Deliver a strong, precise spark to keep every cylinder firing with the DENSO Auto Parts Direct Ignition Coil (P/N 673-8210). This coil-on-plug unit drops in as a direct-fit replacement for a wide range of Genesis, Hyundai and Kia models, including the 2019-2023 Genesis G70, 2015-2019 Hyundai Sonata, 2016-2020 Kia Optima and 2018-2021 Kia Stinger — see the Buyer’s Guide tab for the full list of 14 applications.
A direct ignition coil steps up the vehicle’s low battery voltage into the high voltage needed to jump the spark plug gap, mounting directly over the plug so there are no separate plug wires to fail.
- Coil-on-plug design: seats over an individual spark plug to deliver spark directly to that cylinder.
- High-voltage output: transforms battery voltage into the ignition energy each plug needs to fire.
- Direct-fit replacement: installs in place of the original coil on the listed applications.
Common signs a coil may need replacing include engine misfire, rough idle, hesitation and a check engine light. If a failed ignition coil is the cause, this unit replaces it — diagnose the misfiring cylinder before ordering to confirm the coil is at fault.
Interchange: Manufacturer part number 673-8210 (also 6738210).
