Help deliver a strong, consistent spark with the MANDO Direct Ignition Coil, part number 21A0126. It converts the vehicle's low-voltage electrical supply into the high voltage the ignition system needs to fire the spark plug. It fits many Hyundai and Kia vehicles, among them the 2017-2019 Hyundai Elantra 2.0L, 2016-2017 Hyundai Sonata 2.0L and 2017-2020 Kia Optima 2.0L. It is a direct-fit replacement for the listed applications with the L4-2.0L engine. See the "Vehicles it fits" section for the full list of vehicles.
A direct ignition system has no distributor, so the coil's high-voltage output goes to the spark plug without one. Signs a coil may need replacing include engine misfires, a rough or shaky idle, hesitation when accelerating, hard starting, reduced fuel economy and an illuminated check engine light. These symptoms can also come from worn spark plugs, fuel delivery problems or wiring faults, so diagnose the cause first. If a failed ignition coil is the cause, the MANDO 21A0126 is designed to replace it.
