The Importance of Spark Plugs
Your spark plug is small, but it is responsible for allowing your engine to work as it should. Spark plugs are responsible for igniting the air and fuel mixture in your engine, and this ignition causes the engine to produce power.
Without spark plugs, your vehicle’s engine will not function as it should. Even if only one of the spark plugs are faulty, it will negatively impact your driving experience and can damage your fuel injectors and cylinders if you continue driving with it.
Because spark plugs play such a vital role in your vehicle’s health, you always need to keep them in working condition.
How Much Do Spark Plugs Cost?
Spark plugs are relatively cheap. Most spark plug sets range anywhere from $12 to $600. The price will largely depend on the vehicle in question. Most residential vehicles, such as Subaru, Nissans, and Hondas, require cheap spark plugs that cost between $20 and $200.
Where you purchased the set will impact the cost too. Walmart, Amazon, and other similar stores sell the cheapest spark plugs, some being as cheap as $12. Purchasing from a specific mechanic sometimes costs more, but you know you are getting a high-quality spark plug.
You also have to consider the spark plug material. Spark plugs are normally made from copper, platinum, double platinum, or iridium. Copper is the least efficient, with iridium being the most efficient. The more efficient the spark plug is, the more expensive it will be.
If you’re trying to get an exact idea of how much your spark plug will cost, consider your vehicle. This will give you a more concrete estimation based on the vehicle in question. Here’s a look at the average cost of spark plugs per set based on vehicle type:

Additional Costs to Anticipate
If you have no mechanical experience, you will have to hire a mechanic to install the spark plug for you.
Hiring a mechanic is what will make replacing the spark plugs more expensive. Labor costs will largely depend on the mechanic and your vehicle. Most labor costs range anywhere from $50 to $600, but most mechanics fall between the $50 and $200 range.
Keep in mind that in addition to the labor cost, you will have to pay for the spark plug separately. Some mechanics will give you a deal if you purchase the spark plug from them.
Here is an estimation of how much labor will cost based on vehicle type. Keep in mind this is just the labor cost, and not the spark plug cost plus labor cost.

How Often Should I Replace Spark Plugs?
Most spark plugs are designed to last a long time and most models only need to be replaced every 80,000 to 100,000 miles.
That being said, you will want to consult your owner’s manual to find out how frequently your specific spark plugs need to be changed. Some spark plugs need to be changed as soon as every 30,000 miles, but some can last up to 100,000 miles. Considering your vehicle and your individual spark plugs will give you a better idea of when they need to be replaced.
That being said, do not hesitate to get your spark plugs evaluated if your engine is showing any problems. Here are the most common signs that your spark plug needs to be replaced:
- Vehicle is having difficulty starting
- Engine knocks
- Rough idling
So, get your spark plugs replaced either whenever they are showing signs of damage or whenever your manufacturer recommends if no signs of wear show up before.
Can I Replace My Own Spark Plugs?
Because the labor cost of spark plugs is the most expensive part of getting them replaced, you might be wondering if you can replace spark plugs on your own. The answer is yes. You can replace spark plugs on your own, and the job is relatively easy. This will help to save you some money while still keeping your vehicle in working condition.
How To Care For Your Spark Plugs
Due to the nature and position of spark plugs, there’s very little you can do to maintain them. Properly caring for your vehicle and getting frequent, high-quality oil changes will help to keep your spark plugs working as they should. Other than that, spark plugs are durable and will be able to last a long time.
Additionally, make sure to care for the engine specifically. In addition to getting your oil changed, check for oil leaks or excessive fuel. These sorts of engine issues can damage spark plugs if they go on for a long time.
Predicting the cost of getting spark plugs replaced can be a bit difficult. The make and model of your vehicle, as well as the spark plug type, will impact the final price. You will also have to consider the cost of labor if you do not know how to replace spark plugs on your own.
Overall, expect to spend under $200 on spark plugs, but the labor normally costs around $100 or more so installing spark plugs on your own can be a great way to save some money. No matter how you decide to get your spark plugs replaced, make sure to replace them when needed since they are an integral part of your vehicle.
