Your car’s spark plugs play a vital role in igniting the fuel-air mixture in the engine cylinders, ensuring smooth starts and efficient engine performance. Over time, spark plugs wear out and can lead to engine misfires, poor fuel economy, or sluggish acceleration. Replacing them is a key part of routine car engine repair, and it’s a task many drivers can do themselves—with the right guidance.

At Perfecto, a trusted car workshop in Sharjah and Dubai, we recommend checking your spark plugs regularly and replacing them as needed. Here’s a quick guide to help you through it.

Step-by-Step: Changing Your Car’s Spark Plugs

1. Gather Tools and Parts
You’ll need new spark plugs (make sure they match your car’s specifications), a ratchet with a spark plug socket, a gap gauge, and possibly a torque wrench.

2. Locate the Spark Plugs
Open the hood and find the spark plug wires or ignition coils, usually on top of the engine. Remove them carefully to expose the spark plugs beneath.

3. Remove Old Spark Plugs
Using your ratchet and spark plug socket, turn the plugs counterclockwise to remove them. Be gentle to avoid damaging the threads inside the cylinder head.

4. Check and Set the Gap
Use a gap gauge to ensure the new spark plugs have the correct gap between the electrodes. Adjust carefully if needed, according to your vehicle manual.

5. Install New Spark Plugs
Thread the new plugs in by hand first to prevent cross-threading, then tighten with your ratchet or torque wrench to the manufacturer’s recommended torque.

6. Reconnect Wires or Coils
Secure the ignition coils or wires back in place, ensuring they’re connected firmly.
