• Ratchet: A ratchet will help you turn the socket wrench.
• Extension bar: An extension bar will provide extra reach for accessing the spark plugs.
• Spark plug gap tool: This tool will help you adjust the gap of the new spark plugs to the manufacturer’s recommended specifications.
• Gloves: Protect your hands from dirt and grease.

Safety Precautions

Working on your car requires a certain level of caution. Here are some safety precautions to keep in mind:

• Park your car on a level surface and engage the parking brake.
• Disconnect the negative terminal of the battery. This will prevent any electrical shocks.
• Allow the engine to cool completely before working on it. A hot engine can cause burns.
• Be careful when working around moving parts.
• Use caution when handling tools and avoid dropping them on the engine.

Step-by-Step Guide to Changing Spark Plugs

Now that you have the necessary tools and have taken the necessary precautions, let’s get started:

1. Locate the Spark Plugs:

• Open the hood of your Elantra and locate the engine compartment.
• The spark plugs are typically located on top of the engine, near the center.
• You’ll likely see a coil pack sitting on top of each spark plug.

2. Disconnect the Coil Packs:

• Carefully unplug the electrical connectors from the coil packs.
• These connectors are usually secured with a clip or a latch.
• Pull gently on the connector to disconnect it from the coil pack.

3. Remove the Spark Plugs:

• Use the socket wrench and extension bar to loosen the spark plugs.
• Turn the socket wrench counterclockwise to loosen the plugs.
• Once the plugs are loose, you can use your fingers to remove them completely.

4. Inspect the Old Spark Plugs:

• Examine the old spark plugs for signs of wear and tear.
• Look for excessive buildup, cracks, or erosion on the electrodes.
• If the plugs are worn out, it’s time to replace them.

5. Install New Spark Plugs:

• Before installing the new spark plugs, use the spark plug gap tool to adjust the gap to the manufacturer’s specifications.
• Thread the new spark plugs into the spark plug holes by hand.
• Use the socket wrench and extension bar to tighten the spark plugs to the recommended torque.
• The torque specifications for your 2013 Elantra can be found in your owner’s manual or online.

6. Reconnect the Coil Packs:

• Carefully connect the coil packs to the spark plugs, ensuring they are securely in place.
• Make sure the connectors are fully seated and locked.

7. Reconnect the Battery:

• Connect the negative terminal back to the battery.

8. Start the Engine:

• Start the engine and listen for any unusual noises or misfires.
• If everything is working properly, let the engine run for a few minutes to allow the new spark plugs to heat up.

Tips for Success

• Clean the spark plug wells before installing the new spark plugs. This will help prevent dirt and debris from entering the combustion chamber.
• Use a thread sealant on the spark plugs before installing them. This will help prevent leaks.
• Don’t overtighten the spark plugs. Overtightening can damage the spark plug threads.
• If you’re not comfortable changing the spark plugs yourself, take your car to a mechanic.
