## How Long Do Car Engine Spark Plugs Last?
Spark plugs are a vital part of your car’s engine. They provide the spark that ignites the air-fuel mixture in the cylinders, which creates the power that drives your car. Spark plugs need to be replaced periodically, as they can wear out over time. The lifespan of spark plugs can vary depending on a number of factors, including the type of spark plug, the driving conditions, and the maintenance schedule.
How Do I Know When My Spark Plugs Need to Be Replaced?
There are a few signs that can indicate that your spark plugs need to be replaced. These include:
* **Engine misfires:** Misfires occur when the spark plugs fail to ignite the air-fuel mixture in one or more cylinders. This can cause the engine to run rough, lose power, and produce a knocking sound.
* **Hard starting:** If your car is difficult to start, it could be a sign that the spark plugs are worn out.
* **Poor fuel economy:** Worn-out spark plugs can cause your car to use more fuel than normal.
* **Increased emissions:** Worn-out spark plugs can also lead to increased emissions, as the engine is not able to burn the air-fuel mixture efficiently.
How Often Should I Replace My Spark Plugs?
The lifespan of spark plugs can vary depending on a number of factors, including the type of spark plug, the driving conditions, and the maintenance schedule. However, most spark plugs will need to be replaced every 30,000 to 60,000 miles.
* **Conventional spark plugs:** Conventional spark plugs are the most common type of spark plug. They are made from copper and have a lifespan of 30,000 to 60,000 miles.
* **Platinum spark plugs:** Platinum spark plugs are made from platinum and have a longer lifespan than conventional spark plugs. They can last up to 100,000 miles.
* **Iridium spark plugs:** Iridium spark plugs are made from iridium and have the longest lifespan of all spark plugs. They can last up to 120,000 miles.
If you drive in a lot of stop-and-go traffic, your spark plugs may need to be replaced more often. This is because stop-and-go traffic puts more stress on the spark plugs, causing them to wear out faster.
It is also important to follow the maintenance schedule recommended by your car’s manufacturer. The manufacturer will specify how often the spark plugs should be replaced.
How Much Does It Cost to Replace Spark Plugs?
The cost to replace spark plugs can vary depending on the type of spark plugs you choose and the labor costs of your mechanic. However, you can expect to pay between $100 and $300 for a spark plug replacement.
Can I Replace Spark Plugs Myself?
Replacing spark plugs is a relatively simple job that most people can do themselves. However, it is important to follow the instructions in your car’s owner’s manual carefully. You will also need to have the right tools, including a spark plug wrench and a gap gauge.
If you are not comfortable replacing spark plugs yourself, you can take your car to a mechanic.
