Spark plugs are an essential component of any gasoline-powered engine. They are responsible for creating the spark that ignites the fuel and air mixture in the engine's cylinders. However, there are a few precautions that you should take when using spark plugs to ensure their proper performance and longevity.

Thirdly, you should always use a torque wrench to tighten the spark plugs to the manufacturer's recommended torque specs. Over-tightening the spark plugs can damage the threads on the cylinder head, while under-tightening them can cause the plugs to vibrate loose and potentially damage the engine.
