Not everybody knows when the spark plugs need replacing. It’s not often, after all, that today’s cars need this service conducted. Even today’s modern cars do need to have new spark plugs installed periodically. Find out everything you need to keep your car’s spark plugs in good working order.

Spark Plugs

Your spark plugs are one of the most important parts of your engine. Without a functioning spark plug, your engine can’t run. So what does a spark plug do? It sparks. Electricity travels from a battery into a coil that allows power to build up to as much as 45,000 volts. From there the electricity goes into the spark plug. At the end of the spark plug that is inside the cylinder, the electricity jumps from one electrode to another, creating a spark. This is what ignites the fuel in the cylinder, creating combustion, and driving the piston.

There was a time when your spark plugs needed to be replaced every couple of years. Today is different. Spark plugs are better made, and more durable, so they last longer. Engines are also better designed and use computers to precisely control combustion, so there isn’t residual carbon buildup in the cylinders that used to plug up spark plugs.

Today’s cars produce more power with less gas, and a big reason for that is better computers, sophisticated sensors, electronic ignition, and of course, better spark plugs. These days you don’t need to replace your spark plugs ever year or two, but you do need to change them periodically. You should check your vehicle’s owner’s manual to see when spark plug replacement is recommended. Usually it will be wrapped into a maintenance interval along with other tasks such as oil changes, tire rotations, and brake service.
