If your spark plugs are gapped incorrectly, it can cause all sorts of engine problems. Here’s how to make sure they’re properly gapped. First, find the correct gap for your vehicle using a spark plug gap chart.
Most charts are organized by make and model of vehicle. Once you know the proper gap, use a feeler gauge to check the gap on your spark plugs. If the gap is too wide, gently bend the side electrode until it’s the correct distance from the center electrode.
If the gap is too narrow, tap lightly on the side electrode with a small tool to widen it slightly.
- Remove the spark plug wire from the spark plug
- Clean the area around the spark plug with a clean rag
- Use a ratchet and socket to remove the spark plug from the engine
- Inspect the spark plug for any damage or debris
- Gap the new spark plug using a feeler gauge
- Hand-tighten the new spark plug into the engine, then use a torque wrench to finish tightening it to specifications
- 7 Reattach the spark plug wire and test-start the engine to check for proper operation

How Do You Close Spark Plug Gap Without Tool?
If your spark plug gap is too wide, your engine will misfire. You can fix this problem without a tool by gently bending the side electrode until it’s the correct distance from the center electrode. Be careful not to bend the electrode too much, or you could damage the spark plug.
What Happens If My Spark Plug Gap is Too Big?
If your spark plug gap is too big, it can cause a number of problems. First, the spark may not be able to jump the larger gap, which can lead to misfires. Second, if the spark does jump the larger gap, it will be less intense, which can affect engine performance.
Finally, a large spark plug gap can also cause premature wear on the plugs themselves.
What Happens If You Don’T Properly Gap Your Spark Plugs?
If you don’t properly gap your spark plugs, the engine may misfire. The air/fuel mixture may not ignite correctly, and the engine may run leaner than it should. This can lead to increased emissions and decreased fuel economy.
How to Adjust Spark Plug Gap Without Tool
If your spark plugs are too far apart, they won’t create a strong enough spark to ignite the fuel in your engine. This can lead to misfires and poor performance. On the other hand, if they’re too close together, they can cause pre-ignition and damage to your engine.
So it’s important to adjust the gap on your spark plugs periodically to ensure optimal performance.
The good news is that you don’t need a special tool to adjust the gap on most spark plugs. A feeler gauge will do the trick.
Simply insert the appropriate size gauge between the electrode and ground strap of the plug and tighten or loosen the connection until you’ve achieved the correct gap.
Keep in mind that some plugs may require a different gap than others, so be sure to consult your owner’s manual or service manual for specific instructions. And always remember to replace any damaged or worn out spark plugs as soon as possible!
Conclusion
When a spark plug gap is too wide, it can cause misfires and decreased performance in your engine. You may need to adjust the gap on your spark plugs if you notice these problems.
To close the gap on a spark plug, you’ll need a feeler gauge.
Insert the narrow end of the feeler gauge into the gap and then bend the other end until it rests against the electrode. Use pliers to squeeze the electrode until the gap is closed.
