It's important to maintain the correct spark plug gap to ensure your vehicle's engine is running properly. If the gap is too small, the spark may not be strong enough to ignite the air/fuel mixture, causing misfires and reduced engine power. If the gap is too large, the spark may not be able to jump the gap, resulting in a loss of spark and a dead cylinder.
You can check the spark plug gap using a spark plug gap gauge. To do this, simply insert the gauge between the center electrode and the ground electrode of the spark plug. The gap should be equal to the thickness of the gauge. If necessary, you can adjust the gap by bending the ground electrode.
Always refer to your vehicle's owner's manual for the specific spark plug gap for your model and year.
