When to Change Spark Plugs in Your Car?


Spark plugs are small plugs that basically provide the spark enabling the car’s engine to produce power. Therefore, if your car is working well then you have maintained it well. Two main types of spark plugs are present, conventional spark plugs and long-life spark plugs. Conventional spark plugs require to be replaced after 30,000-50,000 miles whereas long-life spark plugs need to be changed between 60,000 and 150,000 miles.

This spark plugs however need to be changed as they are a very important device and with time they also wear out. Moreover, due to the contaminated spark plug, your ignition coil can also fail and thereby not create an electric spark.

However, the question that arises is that, when is it necessary to change spark plugs in your car?

Can you see the signs that your spark plug has worn out?

Your car is hard to start

If you are facing difficulty in starting your car then this is a sign that your spark plug has worn out. If earlier your car would start smoothly but now it’s not the same as before then you need to take this into account and get your spark plug changed.
