Where does the spark plug go in an engine?
The opposite end of the spark plug has two exposed electrodes that are located inside the cylinder. The electrical current from the ignition system travels to the plug’s center electrode. A high voltage spark jumps a small gap to reach the second electrode. That spark ignites the fuel-air mixture inside the engine cylinder.
Are there still spark plugs in newer cars?
Some later models have an ignition system without a distributor, but they still have traditional spark plug wires. Depending on automaker, those harnesses started to disappear in the late 1990s/early 2000s. Newer vehicles have a coil-on-plug ignition system that eliminates electrical problems caused by worn-out spark plug wires.
