How do you gap a spark plug with a coin?
Most measuring tools will also feature a flat edge typically used for bending the bottom electrode on the spark plug to adjust the gap slightly. A coin-style gap measure is usually the cheapest option, and works by running the edge of the “coin” through the gap until you reach a point where it stops.
Is there a way to make a gap in a spark plug?
You can reduce or adjust accordingly. Simply tap plug against surface and make the gap come to your required measurement. You need to be gradual and careful while doing so. There are aluminum insulator or porcelain that should not get damaged. Never try using the ramp for making any kind of gap at all.
When does a spark plug need to be widened?
Determine if the gap needs adjusting. If the tool passes through the gap without touching the electrodes at the appropriate measure, your gap is too wide. If you can’t fit it between the electrodes, the gap is too small and needs to be widened some. If it fits closely to the specified measurement, you’re safe to install the spark plug.
Do you need to gap iridium spark plugs?
Most spark plugs and iridium plugs manufactured today don’t need to be gapped prior to installing them. If you’ve got a custom modified engine, though, you might be interested in checking or installing plugs at a different spacing.
How do you measure the distance between spark plugs?
Turn off all power to the spark gap apparatus. For example, to measure a spark plug, turn off the engine and remove the plug. Measure the distance in centimeters between the electrodes in the spark gap with the ruler.
Do you need a tool to gap spark plugs?
Spark plug gapping is not an easy job to do if the right tool is not there with you. Yes, the gap spark plug tools that are available might feel too extra to buy separately. However, there are some tools that are really great at handling delicate material. The great part is these do not cost you a fortune.

What does it mean when spark plug is pre gapped?
Pre-gapped only means that the device is pre-measured to work in a variety of engines. Therefore, always measure the gap to ensure maximum efficiency and longevity of the plug in your specific engine. There are a few types of gapping tools you can use.
Is it OK to use coin-style spark plugs?
Those coin-style gap tools may not always be the best option. While those tools are OK for traditional copper/nickel spark plugs, many plug manufacturers have moved towards precious metals.
