Spark Plugs and their Maintenance

Spark plugs are little components that are frequently taken for granted while being crucial to the operation of your car. Your automobile most likely wouldn’t be able to run at all without correctly functioning spark plugs. In this blog, our automotive specialists will go deeper into the significance of spark plugs, what they perform, and how to determine when it might be time to replace them.

What Do Spark Plugs Do?

Your engine is a really amazing device that uses gasoline as an energy source to create movement. Yet how does it accomplish this? Internal combustion, a theory, is the solution. Your car’s fuel must be released for your engine to convert it from a source of potential energy into a source of kinetic energy, and it does this through combustion.

This process is initiated by the engine cycle. During the engine cycle, your valves fill your cylinder with a combination of fuel and air that, when combined, is extremely explosive. This combination is compressed to a very small volume when the piston in your engine rises, releasing even more potential energy. When the piston is at its highest point of compression, your engine ignites this mixture with a tiny spark, causing an explosion that pulls the piston back down and turns the crankshaft in your engine to generate the power that propels your automobile forward.

The spark that ignites the air/fuel mixture and causes the explosion that propels your engine into action is provided by your spark plugs. These tiny, straightforward plugs produce an electrical arc between two leads that are not in contact but close enough to allow current to pass through the space between them. Your ignition system includes your spark plugs as well as the electrical and timing components that power them.

Your spark plugs are typically comprised of materials that are incredibly resilient and can sustain countless explosions before wearing out or needing to be changed. However, it is true that corrosion and explosions over time result in weaker or smaller sparks, which reduces your engine’s performance and may also cause misfiring or failure to fire.

When Should I Replace Them?

Today, the majority of manufacturers will fit “extended-life” spark plugs at the factory. They cost just a little bit more than a regular plug, and customers love the sound. Spark plugs with an extended lifespan are typically rated for a lifespan of about 100,000 miles. The space between the two leads starts to grow as these plugs near the end of their useful lives, which causes decreased efficiency and the potential for misfiring. If your plug corrodes to the point where it breaks, the interior of your engine cylinder could sustain catastrophic damage, necessitating a very costly repair.

In order to find out how long a lifespan your spark plugs are rated for, make sure to examine the owner’s manual for your car. Never let the spark plugs’ rated mileage exceed that.

Methods for Choosing New Ones

Make sure you choose the proper spark plugs for your car when choosing new ones. Most auto parts stores should be able to assist you with this, and you’ll have a wide variety of models to pick from. Although they often cost more than counterparts made of less expensive metals like copper, those made of precious metals like platinum or iridium typically have superior wear resistance.

Cheaper spark plugs could cost as little as $2 or $3, whilst quality plugs made of precious metals could cost as much as $20 or $25 each.

Choose the same brand and model that the car came with as a general rule of thumb.
