When To Change Spark Plugs

If your car has been running rough or not at all, one of the first things you should be checking is if your spark plugs need to be changed. Spark plugs are designed to ignite fuel in a controlled fashion that ensures an engine can smoothly run without any issues.

The lifespan of a spark plug varies from vehicle to vehicle and depends on how often it’s used. For example, someone who drives their car every day will need new spark plugs more frequently than someone who only drives once a week. Keep reading for some tips on when to change your spark plugs!

The best way to know when you will need new spark plugs is by following recommended maintenance intervals listed in the owner’s manual for your specific make and model of car.

When To Replace Your Spark Plug? 

Spark plugs are an essential part of any car engine. They ignite the fuel mixture in the cylinders and help provide power for acceleration, deceleration, and turning. If they wear out or get dirty, they can cause a misfire, leading to more severe problems with your vehicle.

It’s essential that you keep up on the maintenance so that these don’t happen. It is best to replace them every 30,000 miles or so, depending upon the type of spark plug.

Usually, there are two types of spark plugs- conventional spark plugs and long-life spark plugs. 

Conventional Spark Plugs

The lifespan of a conventional spark plug is generally between 30,000 and 60,000 miles. This can vary depending on the type of engine oil used in the vehicle. If you are experiencing any difficulty with starting or idling, it may be time to have your car’s spark plugs replaced.

Long-Life Spark Plugs

Long-life spark plugs such as Iridium spark plugs are designed to last up to 1,50,000 miles. They’re a good choice for drivers who want the convenience of not having to change their spark plugs as often. Therefore, they can be changed after that.

Symptoms Of A Bad Spark Plug That Calls For Immediate Replacement

 Spark plugs wear over time and need to be replaced. If they’re not, it can lead to engine damage or a breakdown. If you’ve been noticing a lack of power in your engine, or if it seems to be running rough, then there is a good chance that one of the spark plugs has gone wrong, and it needs to be replaced.

Also, the decrease in performance could be because of a bad spark plug. Other symptoms of a bad spark plug include hard starting, stalling, misfires, rough idle, hesitation on acceleration, and reduced fuel economy.

As A Precautionary Measure, Should You Change Your Spark Plugs Earlier?

The life of the spark plug is dependent on many factors, including driving habits and engine condition. Most manufacturers recommend that spark plugs be replaced every 30,000 miles or 24 months. If you’re not sure when to replace them, consult your owner’s manual for more information.

For instance, if you find out that your long-life spark plugs are due at 100,000 miles and the dealer advises changing them by 50,000 miles, then it’s too early. Also, if your engine is running well on gas, feel free to wait until it reaches the recommended mileage before you change out spark plugs.

On the other hand, changing your spark plugs early could save money in the long run by preventing unnecessary repairs and maintenance costs down the road. It will also help keep your car running smoothly so it can last longer. 

Can Spark Plugs Be Cleaned For A Longer Life? 

Spark plugs can become dirty over time, which can lead to a decrease in performance and efficiency. There are many ways that you can clean spark plugs; some methods include using compressed air or a wire brush attachment on a drill to remove dirt from inside the plug’s metal casing.

You could also use brake cleaner spray or WD-40 as these chemicals will dissolve any deposits on the surface of the plug’s ceramic insulator tip (the part that touches the engine). And if all else fails, try soaking them overnight in carburetor cleaner diluted with water!

However, cars with long-life spark plugs are not serviceable, so they’re simply replaced altogether.

While Replacing Spark Plugs, Do Spark Plug Wires Also Need To Be Changed?

Spark plug wires are an essential part of the ignition system. They carry electricity from the distributor or coil pack to each cylinder in your engine. If they’re not working properly, it can cause misfires and a loss of power. When replacing them, you should always replace both at once for safety reasons. 

Before Replacing, Check The Condition Of The Spark Plug

A mechanic can check the condition of the spark plugs. This will help them determine if they need to be replaced or not. If they do, it is crucial that you get this done as soon as possible before your car starts having problems starting and running smoothly. 

Spark plugs should always be inspected for wear and tear to have no problems with how well the engine runs. It is also important because sparks from these devices ignite the fuel inside an engine which helps it run properly, so without them, there would be no way for an engine to work correctly.

When looking at spark plugs, make sure they aren’t cracked or broken and that their insulators aren’t worn down too much either – otherwise, you may need new ones!
