Benefits of replacing spark plugs in a car: It enables complete combustion of gasoline, thereby achieving optimal power output while reducing fuel consumption. Each cylinder in a car engine has one spark plug - a four-cylinder engine has four, and a six-cylinder engine has six, so it's important to confirm the quantity when replacing. It's advisable to replace with the same type of spark plugs originally used in the vehicle to ensure proper compatibility. The function of spark plugs is to ignite the fuel-air mixture. During operation, the electrodes of spark plugs consume electrical energy through spark discharge from areas prone to discharge. Particularly when the center electrode reaches higher temperatures, it undergoes acidic erosion and consumption. The rate of electrode consumption varies depending on the melting point, strength, and hardness of the electrode material.
As a car owner with years of driving experience, I've found that replacing old spark plugs in an aging vehicle brings many benefits. My old car used to shake at low speeds and had sluggish acceleration, but after changing the spark plugs, it became noticeably smoother with much quicker throttle response. Fuel consumption also improved, saving about one liter per 100 kilometers – significant long-term savings. More importantly, it reduces the risk of breakdowns; worn spark plugs can cause ignition failure, especially during cold starts. Regular replacement (e.g., every 50,000 km) ensures more stable engine operation and extends its lifespan. I recommend opting for high-quality platinum or iridium spark plugs – though pricier, their durability offers better value. Never overlook this during routine maintenance to avoid regrets later.
