Regularly checking your spark plugs is essential preventive maintenance. A spark plug usually lasts about 30,000 miles, but cleaning them and maintaining them periodically lets your engine perform better and increases your plugs' lifespan. If you see rust, carbon, gunk, dust, or any type of buildup during the inspection, it may be time to clean them.

Steps for Cleaning The Spark Plugs

Step 1: 

Wait for your engine to cool down.

Step 2: 

Locate the spark plug wires and follow them to the spark plug. Clean any debris or buildup that you might find there.

Step 3: 

Unscrew the spark plug using a socket wrench.

Pro tip - It is best to take out one spark plug at a time to clean it. This will ensure that you don't make mistakes when putting them back in.

Step 4: 

Inspect your spark plugs. If the spark plug is only lightly soiled, you can try cleaning it with sandpaper. You can start by removing any debris on the outside of the spark plug. Next, use 220-grit sandpaper to gently sand away buildup - use a light touch, as you don't want to damage the metal. You can also use a small file to remove any stubborn buildup.

Step 5: 

You can use a wire brush to remove debris from its threads.

Pro tip - You can also use a carb cleaner to clean the spark plug if required!

Step 6: 

After cleaning, you need to check the gap between the plug and the electrode using a spark plug gap tool. You will need to refer to your vehicle's manual for specifications, as each car comes with its manufacturer-recommended gap specs.

Step 7: 

Make sure that the plug is completely dry before reinstalling it. Before you reinstall the spark plug, apply a minimal amount of grease to the threads. The grease will help prevent corrosion and make it easier to remove the spark plugs in the future. Tighten the spark plug by hand until it is snug, and then use a torque wrench to finish tightening. Avoid over-tightening it!

Step 8: 

Start your engine to test your work.
