  1. Park your Hyundai in a safe area, set the parking brakes, and allow the engine to cool down.

  2. Open Hood – Next, open the hood. Clean the area near the spark plugs and around the ignition coils.

  3. Disconnect the negative battery terminal – Since you will be working with the electrical system, it is safe to disconnect the negative battery terminal.
  4. Remove the engine cover – It is held in place with up to four 10mm bolts you can access from the top of the engine. If no bolts are on top of the engine cover, pop up the cover. 
  5. Remove ignition coils – Remove the engine cover and disconnect the ignition coils. Unplug the ignition coil connector by pressing the locking tab and then pulling the connector away.

  6. Use a 10 mm socket to loosen the bolt that secures the coil. This vehicle uses a coil-on-plug design. Therefore, you will have one coil on each spark plug. Pull the ignition coils out once the bolt and connector have been removed. If the ignition coil refuses, try twisting it slightly and lifting it up and out.
  7. Remove the spark plug. Blow dirt away from the spark plug recess before you remove the spark plugs.

  8. Use the spark plug removal tool, ratchet, and a 3/8″ extension to remove the spark plugs from the engine. Rotate counterclockwise to remove the spark plug. You may need a magnetic pickup tool to pull out the spark plug.
  9. Install new spark plugs. It is time to install the new spark plug. Inspecting the gap using a spark plug gapping tool is a good practice. Certain spark plugs may come pre-gapped, while others, such as copper plugs, should be gapped.

  10. Install the ignition coils and connect the electrical connector to each coil. Reinstall the engine cover.
  11. Remove all tools from the engine.
  12. Start the engine and check the operation of the vehicle.

If the check engine light was on due to a bad spark plug or ignition coil, clear the codes with an OBD-II scanner like the YOUCANIC Full System Scanner. For more help, check out the guide on reading and clearing fault codes yourself.
