• Engine longevity: Properly gapped spark plugs help prolong the life of the engine by preventing premature wear and tear on its components.

Measuring the Spark Plug Gap

Measuring the spark plug gap requires a special tool called a feeler gauge. The feeler gauge consists of a series of thin, flat blades of different thicknesses. To measure the gap, slide the feeler gauge between the spark plug’s center electrode and the side electrode. The blade that cannot be inserted without forcing the gauge is the correct thickness for the gap.

Setting the Spark Plug Gap

If the measured gap is not within the manufacturer’s specifications, you will need to adjust it. To do this, gently bend the side electrode of the spark plug until the correct gap is achieved. Be careful not to overbend the electrode, as this can damage the spark plug.

Measuring and setting the spark plug gap is a simple yet crucial step in maintaining a well-functioning ignition system. By ensuring the gap is correctly adjusted, you can improve engine performance, enhance fuel efficiency, and extend the life of your vehicle’s engine. Remember to refer to your vehicle’s owner’s manual for the recommended spark plug gap specifications and seek professional assistance if you encounter any difficulties.
