How do you remove spark plug wires on a 2002 Kia Rio?

To remove spark plug wires on a 2002 Kia Rio, first ensure the engine is cool and disconnect the negative battery terminal for safety. Carefully grip the boot of the spark plug wire near the engine and twist it slightly while pulling it straight off, avoiding pulling on the wire itself. Repeat this process for each wire, taking note of their order for reinstallation. If the wires are stuck, you may use a pair of pliers to gently help pull them off, being cautious not to damage the wire or the plug.
