spark plug

A spark plug is a small but essential part of a car's engine. It fits into the engine's cylinders and creates a tiny, controlled electrical spark. This spark ignites the fuel mixed with air inside the cylinder, causing the explosion that drives the engine's pistons to power the vehicle. Spark plugs are designed to withstand high heat and pressure, ensuring consistent ignition. Properly working spark plugs are crucial for the engine's efficiency, smooth operation, and fuel economy. Over time, they wear out and need replacement to keep the engine running reliably.
