When Should You Replace Your Spark Plugs?
December 28, 2023
A car's spark plugs may be relatively smaller components, but they play a massive role in the vehicle. Like other parts and systems, they require proper maintenance. That said, it is critical to know in advance when you should replace them to ensure that the engine's ignition is working smoothly. Without the spark plugs, the vehicle won't start. Therefore, you need to adhere to a strict routine maintenance schedule and replace the plugs at the right moment.
How Often Should I Replace the Spark Plugs?
The purpose of the spark plugs is simple: engine ignition. They create the spark that ignites the fuel and air mixture to initiate combustion in the engine cylinders. As a result, the engine starts when you turn the ignition key.
Like the water pump, the spark plugs have an extended lifespan, and you won't have to replace them for many years. Still, other issues in the car, such as inaccurate heat ranges and chemical contamination, can cause the plugs to wear, warranting the need for replacement.
Generally, you're required to replace the spark plugs every 30,000 to 90,000 miles. This interval varies from vehicle to vehicle. While spark-plug replacements are relatively straightforward procedures, it's critical to always refer to the manufacturer's manual to identify the proper plug location because automakers fit them at different locations.
