Spark Plugs – Small but Mighty

Spark plugs, although small, are a crucial part of keeping your vehicle in optimal running condition. The purpose of the spark plug is to deliver electric spark to ignite the fuel and air mixture located in the combustion chamber of your engine.

Each spark plug is constructed with multiple parts that allow it to function properly. A voltage ranging from 10,000 to 40,000 volts travels from the distributor to the spark plugs when the engine is started. Over time, the components of the spark plug wear down and cause the spark plug to perform poorly and forces the spark plugs to work harder to achieve the same result as new ones since the worn out metal creates a larger gap. The heat, gasoline and oil in the engine can also shorten the life on your spark plugs.

All spark plugs are not created equal. The cheaper copper spark plugs are designed to last for 10,000 miles, while platinum spark plugs have the potential to last up to 60,000 miles. There are other indicators that may signal it is time to replace your spark plugs such as difficulty starting your vehicle, your vehicle sounds rough when idling, or you have a significant drop in your fuel economy. Old spark plugs also affect your emissions system and can trigger your check engine light. If you have any reason to think that your plugs might be bad, it’s time to get them checked out at Louetta Automotive, the preferred automotive repair shop in the Cypress area.
