Engine spark electrodes are a essential part of your car’s engine, responsible for igniting the combustible air-fuel blend that propels your vehicle. Over time, they deteriorate due to the ongoing exposure to extreme temperatures and electrical loads they face. Knowing when to replace them can help you avoid poor performance, improve gas mileage, and completely avoid engine damage.
Most manufacturers recommend replacing spark plugs every 30k–100k miles, but this range depends heavily on the type of spark plug your car uses and your driving conditions. Copper-core plugs typically need to be changed every 30k–50k miles. These are the prevalent in older vehicles and are more affordable but also have shorter lifespans. Platinum electrodes last longer, often between 60k–100k miles, and are standard on many 2000s–2010s vehicles. Premium iridium electrodes, which are the longest-lasting, can go up to 100k+ miles before needing replacement and are exclusive to newer, high-performance vehicles.
It’s important to check your vehicle’s service guide for the exact recommendation. Some cars have unique schedules based on fuel injection system or fuel composition. If you often make short trips, especially in heavy urban congestion, اتوسرویس داوود your spark plugs may degrade prematurely because the engine fails to warm up fully often enough to eliminate residue. Similarly, if you notice symptoms like engine shaking, hard starts, decreased fuel economy, or cylinder misfires, it could be a sign your spark plugs are worn out and need early replacement than the standard interval.
Even if your spark plugs appear functional, it’s a good idea to have them evaluated during regular maintenance. A qualified auto specialist can check for signs of wear, soot accumulation, or cracks that you might fail to detect. Replacing them proactively can help you avoid more costly engine damage down the line.
In short, don’t wait until your car exhibits symptoms to think about spark plugs. Keeping track of replacement intervals based on your vehicle’s requirements and your commute patterns will keep your engine running smoothly for the lifetime of your vehicle.
