Yes! Modern engines that use gasoline still come with spark plugs. They are situated at the top of the engine cylinder and create a spark of electricity between 10,000 to 30,000 volts. This initiates the ignition of the air-fuel mixture in the cylinder. They provide the energy that starts the engine and then propels the car forward.
Spark plugs have always been a necessary part of gasoline-powered engines. Even with direct fuel injectors, modern gas engines still come with spark plugs, with some being equipped with 100,000-mile plugs. How many spark plugs a car comes with depends on the size of the engine or the number of cylinders. For example, an engine with four cylinders needs four spark plugs, etc.
