When it comes to import auto maintenance, even the smallest components impact your car’s overall performance. Though tiny, spark plugs play a critical role in running your vehicle. And recognizing when they need to be replaced will help you keep your engine running smoothly and avoid the need for expensive repairs.

Import Auto Maintenance Guide to Spark Plugs

What Is a Spark Plug?

With an electrode core made from precious metals, spark plugs provide the essential spark of electricity that ignites the air and fuel mixture in your engine’s cylinders. This combustion then forces the pistons down, enabling the motor to turn. Most spark plugs are less than an inch in size, but without their crucial source of continuous ignition, your car can’t move down the road.

How Long Do They Last?

Just like many other parts of your engine, spark plugs will wear down with time. Most of the wear and tear is to the exposed tip of the electrode core. Copper-tipped plugs usually last about 30,000 miles, while platinum- and iridium-tipped plugs typically have a longer life span of up to 100,000 miles. Eventually, the tip will wear down to the point where it no longer creates enough electricity to power your engine. Failing spark plugs can have a direct and immediate effect on your vehicle’s performance, so routinely checking their condition is a vital part of import auto maintenance.

When Should You Replace Spark Plugs?

While the owner’s manual for your vehicle will provide guidance on when to change out your spark plugs, the timing of replacement may depend on other factors. For instance, erosion may occur well before the part’s anticipated life span has expired. Once damaged, a faulty spark plug can lead to a host of problems — including engine misfires, impaired performance, and poor fuel economy. If your car is difficult to start or exhibits signs of engine surging, lack of acceleration, and higher fuel consumption, these are indicators that it’s time to install new spark plugs.
