Ignition plugs are a critical part of your car’s engine, اتوسرویس داوود responsible for igniting the combustible air-fuel blend that powers your vehicle. Over time, they wear out due to the constant heat and electrical stress they face. Knowing when to replace them can help you prevent reduced engine efficiency, improve gas mileage, and mitigate the risk of engine damage.

Vehicle makers recommend replacing spark plugs every 30,000 to 100,000 miles, but this range is largely determined by the type of spark plug your car uses and your commuting patterns. Copper-core plugs typically need to be changed every between 30k and 50k miles. These are the most common in vintage cars and are more affordable but also wear out faster. Platinum spark plugs last longer, often between 60,000 and 100,000 miles, and are standard on many modern sedans and SUVs. Premium iridium electrodes, which are the highest-performance, can go up to over 100,000 miles before needing replacement and are exclusive to newer, high-performance vehicles.

It’s crucial to check your vehicle’s owner’s manual for the precise interval. Some cars have unique schedules based on combustion chamber configuration or fuel type. If you regularly commute short distances, especially in frequent idling, your spark plugs may wear out faster because the engine remains below ideal heat levels often enough to burn off deposits. Similarly, if you notice symptoms like engine shaking, difficulty starting the engine, higher fuel consumption, or engine misfires, it could be a sign your spark plugs are failing and need attention sooner than the recommended schedule.

Even if your spark plugs show no obvious issues, it’s a good idea to have them inspected during regular maintenance. A qualified auto specialist can check for visible degradation, carbon buildup, or physical deterioration that you might not notice. Replacing them before they fail can prevent more costly engine damage down the line.

In short, avoid delaying until your car exhibits symptoms to think about spark plugs. Staying on top of replacement intervals based on your vehicle’s requirements and your driving conditions will ensure optimal engine performance for the lifetime of your vehicle.
