Do you know what's the most common reason for catalytic converter failure? Usually it's all because of worn-out spark plugs. This component helps your vehicle run properly, while the damaged unit can cause a lot of troubles such as excessive fuel consumption and sluggish performance. The only way to check whether a spark plug needs replacement is by visual examination. As soon as you notice any visual damage, don't hold up and get a new plug.

    Before making a replacement, let's first learn how a spark plug functions. The part consists of several elements: the terminal, insulator, body, and two electrodes (center electrode and ground). Screwed into the cylinder head, the plug provides a spark which is required to ignite the air-fuel mixture. The plug also operates like a heat exchanger as it removes any excessive heat from the combustion chamber. Day after day, the plugs must cope with high pressures, extreme temperatures and constant vibration. And even though they are designed to withstand that, wear and tear is inevitable.

    The spark plugs never fail all of a sudden, instead they gradually wear out. And that is why it's a good idea to know why and how fast spark plugs get damaged. It happens that the engine stumbles and then it doesn't start at all. Sometimes the engine might run and then misfire. The damaged spark plug is likely the culprit. There are various reasons for the failure. The engine condition, the purity of the fuel you usually use, and even the way you drive affect the useful life of the items. Oil buildup, carbon and combustion deposits, lean air/fuel mixtures can all lead to the plug damage. When it happens, let CARiD set your mind at ease and offer the first-class replacements.

    Let's find out how often your spark plugs need inspection and replacement. Well, every 30,000 miles is a normal baseline. But remember that vehicles have different requirements, and the spark plugs may stay healthy for 100,000 miles or even more. Yet when the time comes, just remove the plug and visually examine it. Should you notice glazing, white deposits or excessive electrode wear, the time has come for replacement. It is an easy job to do if you can remove the plugs. But if you are not mechanically inclined or feel like it's a bit complicated task, then visit the nearest auto repair center.

    Here they are - the reasons why you need to change your old plugs. The number one reason is that the new parts maintain high engine performance and efficiency. New plugs also improve cold starting, which allows the engine to effortlessly start in the coldest weather. The third 'why' is that the new spark plugs minimize the risk of the catalytic converter failure. Well, now you see that spark plugs should be replaced when damaged or worn-out. Fix the problem as soon an possible with the repair parts that we've gathered for you at CARiD.

      Performing a Basic Engine Tune Up
      This article will guide you through a generic tune up on most any car or light duty gasoline-powered vehicle built within the last 20 years or so. We will presume that you are tuning up your engine because it has reached the mileage or time point to do so, and that you are NOT performing a tune up to cure an engine performance defect. We make this distinction because not all running/performance issues will be solved via a simple tune up.

      Understanding The Different Types Of Spark Plugs
      Since the dawn of the automobile, spark plugs have been an integral part of gasoline engines because they conduct the electrical energy from a vehicle’s ignition system needed to finalize the combustion process. After the gas/air mixture has been fully compressed inside the cylinder head, spark plugs serve a miniature bolt of lightning to create an explosion which pushes a piston downward.
