Ignition plugs are a vital part of your car’s engine, responsible for igniting the air-fuel mixture that powers your vehicle. Over time, they degrade due to the ongoing exposure to extreme temperatures and electrical loads they face. Knowing when to replace them can help you avoid poor performance, reduce fuel inefficiency, and even prevent engine damage.

Most manufacturers 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 commuting patterns. Copper-core plugs typically need to be changed every 30,000 to 50,000 miles. These are the most common in vintage cars and are less expensive but also degrade more quickly. Platinum spark plugs last up to twice as long, often between 60k to 100k miles, and are found in many mid to late model cars. Iridium-tipped plugs, which are the highest-performance, can go up to 100,000 miles or more before needing replacement and are often used in newer, high-performance vehicles.

It’s essential to check your vehicle’s service guide for the exact recommendation. Some cars have unique schedules based on engine design or اتوسرویس داوود octane rating. If you often make short trips, especially in heavy urban congestion, your spark plugs may degrade prematurely because the engine doesn’t reach optimal operating temperature often enough to cleanse carbon buildup. Similarly, if you notice indicators including rough idling, difficulty starting the engine, poor gas mileage, or engine misfires, it could be a sign your spark plugs are compromised and need early replacement than the manufacturer guideline.

Even if your spark plugs appear functional, it’s a good idea to have them examined during scheduled tune-ups. A mechanic can check for visible degradation, carbon buildup, or cracks that you might overlook. Replacing them proactively can help you avoid more expensive repairs down the line.

In short, avoid delaying until your car starts acting up to think about spark plugs. Maintaining awareness of replacement intervals based on your vehicle’s requirements and your commute patterns will maintain peak combustion efficiency for years to come.
