What is a spark plug?

The spark plug is a piece that produces the spark that causes the mixture between gasoline and air in the cylinders of the car. Depending on the number of cylinders in your car, it may have more or less.

The components of a spark plug are the following:

  • Upper terminal: place where the ignition coil is connected.
  • Main body: high voltage and heat insulator.
  • Thread: to screw the spark plug into the cylinder head.
  • Electrode: origin of that spark that causes the mixture between gasoline and air.

It is important to know the difference between the two types of spark plugs that exist, which are the spark plugs and the glow plugs . The first are those used in gasoline cars and the second in diesel cars, both having the function of helping to start the car.
