All car owners should have a basic understanding of how the main components in their vehicles work. Spark plugs are an example of auto parts that often slip under the radar. Since your car won’t run without them, we’re taking a moment to explain what you should know about them.

What Do Spark Plugs Do?

Spark plugs play a crucial role when starting your car, as they produce a spark of electricity that ignites the combustion. This spark gets the pistons in the engine up and running by igniting the fuel and air mixture.

Do Spark Plugs Need to be Replaced?

Add spark plugs to the list of the many things in your vehicle that eventually wear out and must be replaced. The good news is that if you’re diligent about maintaining your engine, your plugs can easily last up to 100,000 miles.

Can Spark Plugs Go Bad?

Like other parts in your car, spark plugs can fail. Missing engine maintenance, or a bad fuel-to-air ratio caused by a bad sensor, leads to a buildup of carbon that can foul the plugs. If you notice a warning light on the dash, visit a Patriot service center immediately.
