Car Spark Plug

Car spark plugs create the precise electrical spark that ignites the air-fuel mixture in each cylinder thousands of times per minute, converting chemical energy into mechanical power. These small but critical components must withstand extreme temperatures exceeding 2,500°F and intense electrical stress while maintaining consistent performance.
Premium spark plugs feature advanced electrode materials including copper, platinum, iridium, and ruthenium, each offering specific benefits in terms of conductivity and durability. Modern designs incorporate fine-wire center electrodes that produce a larger, more complete spark for improved combustion efficiency.
Symptoms of worn spark plugs include rough idle, misfires, poor acceleration, and reduced fuel economy. Regular spark plug replacement according to manufacturer intervals ensures reliable ignition and maintains engine performance.
