How to GAP a SPARK PLUG properly

Spark plug gap tool I used: https://amzn.to/35KDLFh Alternative tool: https://amzn.to/33Eycqg Yet another tool option: https://amzn.to/32pHRAz Gapping your spark plugs to the correct factory specified gap is essential to help your engine achieve proper combustion. An incorrect spark plug gap can lead to a loss of power, engine hesitation when under power, rough idle and misfiring. Adjusting your spark plug gap is super easy and you can do it yourself with just a single tool and a set of spark plugs. There are essentially three different types of spark plug gapping tools, the coin style gap tool, the wire or wire gauge style gap tool and the feeler gauge style gap tool. Of these three using the coin style gap tool is not recommended because it can easily damage electrodes and break the tips of fine wire spark plugs. A few notes before adjusting your spark plug gap. First of all do not attempt to adjust the gap on used spark plugs, only adjust new spark plug. The other thing is that modified engines where compression has been increased or a turbo or supercharger has been added the spark plug gap needs to be reduced. As a general rule of thumb reduce the gap by 0.004 inches or 0.1mm for every 50 horsepower you add to the engine. Adjusting the gap is super easy. You use the gauges to measure your gap and bend the electrode to increase the gaps using the ends of the wire gauge gap tool. Reducing the spark plug gap is even easier, you simply press the spark plug onto a hard flat surface, or the tool itself, gently and easily to reduce the gap. In case your spark plug gap factory specifications are not listed on the gauges of your gap tool you can use a feeler gauge to correctly measure and adjust the gap.
