What are Spark Plugs?

When it comes to keeping your car running smoothly, spark plugs are a crucial component that should not be overlooked. They play an important role in the engine’s ignition system, and without them, your car simply wouldn’t start.

What are Spark Plugs?

Spark plugs are a critical component of your car’s ignition system. They’re responsible for creating the spark that ignites the fuel in your engine, which in turn powers your vehicle. Spark plugs are located at the top of each cylinder in your engine and are typically accessed by removing a plastic cover or metal cover plate.

 

There are two types of spark plugs: traditional copper spark plugs and more modern platinum or iridium spark plugs. Platinum and iridium spark plugs are typically more durable and long-lasting than copper spark plugs, but they can also be more expensive.

How do Spark Plugs Work?

Spark plugs work by creating a spark that ignites the fuel in your engine. When you turn the key in your ignition, a small amount of electricity is sent to the spark plugs, which in turn creates a spark. This spark ignites the fuel in your engine, which causes your car to start.

 

Over time, spark plugs can become dirty or worn, which can cause misfires, poor performance, and reduced fuel efficiency. That’s why it’s important to inspect and replace your spark plugs on a regular basis.

When to Replace Your Spark Plugs

How often you should replace your spark plugs depends on several factors, including the age of your vehicle, the type of spark plugs you’re using, and your driving habits. As a general rule of thumb, it’s a good idea to replace your spark plugs every 30,000 miles or every 3-5 years, whichever comes first.
