At their core, spark plugs are essential components of your vehicle's ignition system. They are responsible for igniting the air-fuel mixture in the engine's cylinders, which in turn powers the engine. Without functional spark plugs, your car wouldn’t start or run efficiently. They might be small, but they are mighty.
Understanding the symptoms of weak or bad spark plugs is crucial. Here are some common indicators that your spark plugs may need attention:

Reduced Engine Performance: If you notice that your car is not accelerating as smoothly as it used to, weak spark plugs could be the culprit.

So, when should you replace spark plugs? Generally, spark plugs should be replaced every 30,000 to 100,000 miles, depending on the type of plug and vehicle. However, it's always best to consult your vehicle’s manual or a trusted mechanic for specific recommendations.
