Make sure you have the right sparks by checking their lengths.Remove all damaged spark plugs and replace them with quality spark plugs.Removing any parts over the ignition coils/ ignition cables. ![]() To Remove all the ignition cables and coins.However, the principle for replacing the spark plug will remain the same in all car models. You might end up opening different engine parts. Some V-engine models are hard to reach the spark plugs. Some models are easy to replace, while others need you to be more skillful. Copper plugs are substandard and will wear off fast. If you cannot find the same spark plug, then replace it with high-quality spark plugs. Copper spark plugs have a short life compared to platinum or iridium.Īlways replace spark plugs with the manufacturer’s original choice. How long a spark plug lasts depends on the type of the plug. However, motor manufacturers recommend you change them after every 30,000 miles. Spark plugs will serve you for many years and miles without the need to change them.
