Everything You Need to Know About Car Spark Plugs

Hello, curious minds! Have you ever wondered what goes on under the hood of your car? Well, it’s one of the most important components of the engine- a car spark plug.

This small yet mighty device creates the spark needed to ignite the fuel and air mixture in your car’s engine. Without it, the vehicle wouldn’t start or run at all. It’s like the matchstick that starts a fire – without it, there’s no flame!

The heat from the flame in the combustion chamber is dissipated to the cooling system of the engine. Thus, keeping them healthy is necessary- it can help you accomplish your car’s maximum potential.

However, sometimes, spark plugs can go bad faster than normal. And the sad part is that it’s often overlooked or forgotten about until there is an issue with it. But, fear not because in this blog, we will dive into all you need to know about car spark plugs.

Spark Plugs- Types and Working 

Now, that we know that spark plugs emit a bolt of electricity and get your vehicle running, let’s know more about its different types.

For example, there are spark plugs made for high-performance engines, such as those found in sports cars or racing vehicles. These spark plugs are designed to handle higher temperatures and pressures, ensuring that your engine runs smoothly even when you’re pushing it to its limits.

On the other hand, there are also spark plugs made for everyday use, like the ones found in your family sedan. These spark plugs are designed to last longer and perform well under normal driving conditions.

Working- Here’s how they work in detail:

Step 1: You initiate the ignition process.

When you start your car by turning the key or pressing the ignition button, the starter motor engages and cranks the engine.

Step 2: Energy from the battery is converted to a high voltage.

Then, electricity from the car’s battery travels to an induction coil located on the combustion engine, where it is converted to a voltage as high as 45,000 volts before being supplied to the spark plugs.

Step 3: The spark plug generates sparks.

As the voltage increases and is transmitted to the spark plugs, the plugs create a spark that ignites the air-fuel mixture inside the combustion chamber, causing a small and controlled explosion in the gap between the plug’s electrodes.

Step 4: Combustion drives the car.

Once the air-fuel mixture ignites, a chemical reaction occurs, producing an expanded gas or exhaust. The sudden expansion within the combustion chamber generates pressure that moves the car’s pistons, converting chemical energy into kinetic energy required to power the engine.

Step 5: The cycle repeats.

As the car continues to run, the spark plugs repeat this cycle over and over again, ensuring that the car runs smoothly until it reaches its destination.

Bad Spark Plug Symptoms

Keeping an eye out for problems with your spark plugs can save you from engine problems. The following signs can help you discover faulty or worn-out spark plugs-

Decrease in fuel efficiency- Faulty car spark plugs can lead to reduced gas mileage. You’ll find your fuel wasted if your car fails to receive the proper spark at the right time.

Engine misfires- If you notice engine misfires and unusual noises from the piston force, it means the spark plugs are worn-out. Spark plugs firing at the wrong time can lead to engine misfires and loud rattling and knocking sounds.

Reduced car performance- Your vehicle won’t perform at its best if the spark plugs aren’t able to function at 100 percent. So, even when you accelerate or change gears when out for a drive, the spark plugs don’t take a break.

Troubled car start- One of the other bad spark plug symptoms is if you notice trouble in starting your car. Damaged spark plugs make it difficult to deliver the spark needed to start the engine. It can even drain the car’s battery and cause serious engine damage.

So, if you notice that your car is running rough or you’re experiencing any of these issues, it might be time to check your spark plugs.

Car Spark Plug Replacement 

Witnessing any of these problems mentioned above is a clear indication that you need to change the spark plugs in your car. Even if you do not notice any signs of damaged/ worn-out spark plugs, it is recommended to change them every 30,000 miles.

However, depending on the type of spark plug you may even go up to 100,000 miles. A spark plug made of stronger materials like platinum or iridium would last longer than one made up of copper.

Replacing car spark plugs in a timely duration can help you reap many benefits-

  • Fully functioning spark plugs can support a fully functioning combustion system. It can help in achieving consistent production of optimal combustion.
  • Replacing spark plugs after specified intervals can maximize fuel economy.
  • One of the other benefits of spark plug replacement is that it can reduce harmful emissions from the car and consequently reduce air pollution.
  • You can experience smooth and energetic car starts when turning the ignition with new or replaced spark plugs.

Car Spark Plug Cost

Typically, a single spark plug is priced at under $10, but the actual cost can vary depending on the expected lifespan and electrode material. The most expensive spark plugs are those that have platinum or iridium tips and use laser technology, which can cost as much as $25 each.

The price of a set of spark plugs can range from $16 to $100, depending on the type of spark plugs required and the number of cylinders in the engine. It’s worth noting that certain specialized engines may require two spark plugs per cylinder, so this should be considered when calculating the overall cost.

However, the average car spark plug cost replacement is $60 to $250.

Wrapping Up

Not having enough knowledge about spark plug replacement within time can take a toll on your pockets and cost you fortunes to buy a new engine! Yes, you read it right. Not replacing bad spark plugs can cause engine damage.

In such a situation, it is advisable to choose a used engine for your car. It can boost your car’s performance and allow you to drive extra miles without spending much. They are affordable and widely accessible.
