A »Spark plugs ignite the air-fuel mixture in an engine's combustion chamber by generating a high-voltage spark. When the spark plug receives an electrical charge, it creates a spark between the center and ground electrodes, igniting the air-fuel mixture and initiating combustion, which powers the engine.

A »Spark plugs ignite the air-fuel mixture in your engine by producing a high-voltage electrical spark. When the engine's piston compresses the mixture, the spark plug's electrodes create a spark strong enough to ignite it, setting off a controlled explosion. This explosion pushes the piston back down, generating the power needed to turn the engine's crankshaft and ultimately drive your vehicle. It's a tiny but mighty part of your car's ignition system!

A »Spark plugs ignite the air-fuel mixture by generating a high-voltage spark between their electrodes, which is produced by the ignition coil. This spark ignites the compressed air-fuel mixture inside the engine's combustion chamber, causing a small explosion that powers the engine.
