How do you change the spark plugs in a 2007 Kia Sorento?

To change the spark plugs in a 2007 Kia Sorento, first, ensure the engine is cool and disconnect the battery. Remove the ignition coil by unscrewing it and gently pulling it out to access the spark plug. Use a spark plug socket and ratchet to unscrew the old spark plug, then install the new one by hand to avoid cross-threading, followed by tightening it with the socket. Reattach the ignition coil and reconnect the battery to complete the process.
