제목| What’s the Ideal Spark Plug Replacement Interval?

Ignition plugs are a vital part of your car’s engine, charged with initiating the fuel-air combination that propels your vehicle. Over time, they wear out due to the ongoing exposure to extreme temperatures and electrical loads they endure. Knowing when to replace them can help you avoid poor performance, reduce fuel inefficiency, and completely avoid engine damage.

Vehicle makers recommend replacing spark plugs every between 30k and 100k miles, but this range is largely determined by the plug specification your car uses and your driving conditions. Basic copper electrodes typically need to be changed every 30,000 to 50,000 miles. These are the widely used in pre-2000 models and are more affordable but also have shorter lifespans. Platinum electrodes last longer, often between 60,000 and 100,000 miles, and are standard on many 2000s–2010s vehicles. Premium iridium electrodes, which are the most durable, اتوسرویس داوود can go up to 100,000 miles or more before needing replacement and are often used in newer, performance-tuned vehicles.

It’s essential to check your vehicle’s owner’s manual for the manufacturer-specified timeline. Some cars have customized replacement cycles based on combustion chamber configuration or fuel type. If you frequently drive short distances, especially in heavy urban congestion, your spark plugs may wear out faster because the engine doesn’t reach optimal operating temperature often enough to eliminate residue. Similarly, if you notice symptoms like rough idling, hard starts, higher fuel consumption, or engine misfires, it could be a sign your spark plugs are worn out and need early replacement than the recommended schedule.

Even if your spark plugs show no obvious issues, it’s a recommended step to have them evaluated during scheduled tune-ups. A technician can check for electrode erosion, soot accumulation, or cracks that you might fail to detect. Replacing them before they fail can prevent more major mechanical issues down the line.

In short, never postpone until your car starts acting up to think about spark plugs. Maintaining awareness of replacement intervals based on your vehicle’s requirements and your driving conditions will maintain peak combustion efficiency for the lifetime of your vehicle.
