What Causes Spark Plugs to Wear Out?

Spark plugs wear out over time due to various factors. Repeated sparking and exposure to combustion byproducts cause natural wear, leading to electrode and insulator deterioration. Carbon deposits from combustion can accumulate on the spark plug electrodes, reducing their effectiveness. Overheating, incorrect gaps, fuel additives and contaminants, and long service intervals can also contribute to spark plug wear. To prevent premature wear, regular inspections, proper maintenance, and using the correct spark plugs are crucial. If you notice poor engine performance, replacing the spark plugs may be necessary.

Other Interior Parts

  1. Starters

    The starter plays a crucial role in initiating the engine's ignition process. When the ignition key is turned, starters quickly engage, cranking the engine into life by meshing with the flywheel.

  2. Alternators

    Alternators convert mechanical energy into electrical power. They are mounted within the engine, and they produce a steady stream of electricity to recharge the battery and power various vehicle systems.
