Gather Your Tools and Materials
Before you begin, make sure you have the following tools and materials on hand:
- New spark plugs: Consult your Suzuki Swift’s owner’s manual or a reliable online source to determine the correct spark plug type and gap for your specific model and year.
- Socket wrench set: You’ll need a socket wrench that matches the size of your spark plugs.
- Spark plug gap tool: This tool is used to adjust the gap between the spark plug electrodes to the manufacturer’s specifications.
- Torque wrench: A torque wrench is essential for tightening the spark plugs to the correct specifications.
- Gloves: Protect your hands from dirt and grime.

Safety First: Important Precautions
- Disconnect the battery: Before working on your car’s ignition system, always disconnect the negative (-) terminal of your battery to prevent electrical shock.
- Allow the engine to cool: Never attempt to work on a hot engine. Allow it to cool down completely before proceeding.
- Work in a well-ventilated area: Spark plugs contain lead, which can be harmful if inhaled.
- Use caution around moving parts: Be aware of moving parts, such as the fan belt, and avoid contact with them.
Step 1: Locate the Spark Plugs
Open the hood of your Suzuki Swift and locate the spark plug wires or coil packs. They are typically attached to the top of the engine, near the cylinder head. Your Swift’s owner’s manual will provide a detailed diagram of the spark plug locations.
Step 2: Disconnect the Spark Plug Wires or Coil Packs
- If you have spark plug wires: Carefully pull the wire boot off each spark plug.
- If you have coil packs: Disconnect the electrical connectors from the coil packs.
Step 3: Remove the Spark Plugs
- Use the socket wrench: Place the socket wrench over the spark plug and turn it counterclockwise to loosen the spark plug.
- Remove the spark plug: Once the spark plug is loosened, use your fingers to remove it from the cylinder head.
Step 4: Inspect the Old Spark Plugs
- Check for wear and tear: Examine the old spark plugs for signs of wear, such as excessive electrode wear, carbon buildup, or cracks.
- Note the gap: Use the spark plug gap tool to measure the gap between the electrodes. This will help you determine if the gap was set correctly.
Step 5: Install the New Spark Plugs
- Set the gap: If necessary, use the spark plug gap tool to adjust the gap on the new spark plugs to the manufacturer’s specifications.
- Install the spark plugs: Carefully thread the new spark plugs into the cylinder head, ensuring they are properly seated.
- Tighten the spark plugs: Use the torque wrench to tighten the spark plugs to the specified torque. Refer to your Suzuki Swift’s owner’s manual for the correct torque specifications.
Step 6: Reconnect the Spark Plug Wires or Coil Packs
- Reconnect the spark plug wires: Carefully reattach the spark plug wires to the spark plugs, ensuring a secure connection.
- Reconnect the coil packs: Reconnect the electrical connectors to the coil packs.
Step 7: Connect the Battery and Test
- Connect the battery: Reconnect the negative (-) terminal of the battery.
- Start the engine: Start the engine and listen for any unusual noises or misfires.
- Check for leaks: Inspect the spark plug area for any signs of leaks.
