How often you change spark plugs sometimes depends on vehicular usage. Spark plugs are responsible for creating sparks that ignite the air and fuel in the combustion chamber.
Spark plugs are a very important part of the combustion process in the engine, they are made to be very durable. Plugs are designed to last very between every 80,000 and 100,000 miles in active use.
However, it is important to keep their service every 30,000 miles so as to keep eye on the replace them as soon as it can be. Enough about the spark plugs let’s answer the big question how long will spark plugs last let’s hear what our experts on Cookip auto experts have to say below.
How Often to Change Spark Plugs
The average time for spark plugs to be changed is every 60,000 miles. However, some people say that it should be changed every 20,000 miles.
People often wonder how often they should change their spark plugs. The answer is that it depends on the type of engine you have, the age and make of your car, and how much you drive.
The best way to know when to change your spark plugs is to consult with a mechanic or a professional who can help you figure out what would work best for your specific car. The standard spark plugs are typically used in engines with lower RPMs, while platinum plugs can be used on higher-performance engines.
There are three main types of spark plugs: standard, platinum, and iridium. Iridium plugs should only be used in specialized situations or on older vehicles because they are more expensive than other types of plugs.
Spark plugs are the component that provides power to your motorcycle engine. This is why it is important to change them regularly.
When you change your spark plugs, it is important that you also check the condition of your battery and fuel filter in order to avoid any potential issues. It is recommended to replace your spark plugs every 4,000-6,000 miles depending on how often you ride.
Benefits of Changing Spark Plugs
The benefits of changing your spark plugs are numerous. They include saving money, reducing pollution, and improving fuel efficiency. The process itself is also not difficult, but it does require attention to detail and patience.
A spark plug is a device that provides the spark needed for the combustion of fuel in a combustion engine. The main function of the spark plug is to provide an electric current to ignite the air-fuel mixture in the engine.
The benefits of changing your spark plugs include:
-
better fuel economy.
-
more power and torque.
-
lower emissions.
-
better performance.
-
improved fuel quality.
Spark plug wire is a type of electrical wire used in spark-ignited internal combustion engines. The wire conducts the high-voltage “spark” signal to the spark plugs, providing their ignition without the need for an external power source.
Signs You Need New Spark Plugs
A failing spark plug can be caused by dirt buildup, lack of proper maintenance, or simply old age. The good news is that it’s an easy fix that you can do yourself at home with some basic tools. Some of the symptoms include the following.
- Rough idling
When the spark plug is failing, it fails to deliver the proper amount of spark needed to ignite the air and fuel in the combustion chamber thereby leading to incomplete combustion. Inconsistent combustion will lead to a rough idling engine.
- Difficulty in starting
When starting the car, the ignition switch sends a signal to the starter motor to crank the engine. When the engine turns the spark plugs will then ignite sparks that will ignite the air and fuel in the combustion chamber which generate energy to keep the engine running.
A failing or bad spark plug would not be able to generate the right amount of spark needed to ignite the air and fuel to burn and keep the engine running. When spark plugs fail, they are covered in black sooty which prevents the diode from igniting a spark.
- Reduced acceleration power
Few other components affect the acceleration. You may lose up to 40% of your acceleration power. When your vehicle loses its acceleration power, you tend to use more fuel as well.
- Engine knock
This one is a severe case, and if left unaddressed may lead to significant mechanical damage. You risk damaging the following engine components.
Piston head. An engine knock soon follows the piston head. If the intensity of the knock is immense, it may perforate the piston’s head. Piston compression rings.
Though not as damaging as losing a piston head, this will still need a comprehensive engine repair. Other signs and symptoms of a failing spark plug include a backfiring Engine, poor fuel economy, and a misfiring engine.

Toyota Spark Plug Change Interval
Toyota recommends that spark plugs should be changed every 100,000 miles.
This is a recommendation, not a law. If the car starts running poorly and the owner can’t figure out what the problem is, it might be time to change the spark plugs. In this case, Toyota recommends getting an expert opinion before changing them because there are other possible causes for poor performance such as a dirty air filter or an ignition problem.
The service bulletin was created by using a word document and the Spark Plug Change Interval template that was created by Toyota’s engineering team. The templates are available on the Toyota website and they can be modified according to different types of cars or maintenance schedules.
How Long Will Spark Plugs Last?
Spark plugs are designed to withstand a lot of circumstances including heat to provide spark ignition in the combustion chamber. A spark plug can last as long as 1.5 to 2.5 years this all depends on the mode of vehicular usage.
When your engine is functioning correctly, spark plugs should last between 20,000 and 30,000 miles. The U.S. Federal Highway Administration clocks Americans’ average annual mileage at 13,476.
Break this down into spark-plug life expectancy, and it comes to between 1.5 and 2.25 years. Spark plugs should be replaced as quickly as possible if noticed to be sooty or already worn out.
Can I Replace my Own Spark Plugs?
Yes and no you can and cannot replace your car’s spark plugs all by yourself. Some engines are designed with spark plug compartments being hard to access.
A typical example is a v-6 engine, some of the old models of this engine are poorly designed in a way that you will have to remove the portions of the intake manifold to replace the spark plugs.
But if your engine affords easy access to the rear bank, you can probably do the job yourself. Just be sure you gap the spark plugs properly and use a torque wrench.
Can You Drive with Faulty Spark Plugs?
Can you drive with faulty spark plugs, yes you can drive with faulty plugs with a but. Faulty spark plugs can affect the overall engine performance and cause a significant increase in horsepower.
When plugs are faulty they tend not to create enough spark to ignite the fuel and air in the combustion chamber. If fuel is not completely burnt, it can cause the car to shake, engine performance too will definitely be affected.
A fouled or bad spark plug is a plug that has become covered with a substance like oil, fuel, or carbon or one that is blistered from running too hot. Driving with fouled or bad spark plugs can cause a host of problems for your engine.
What are The Benefits of Changing Spark Plugs?
Spark plugs are responsible for igniting the air/fuel mixture, creating the explosion which makes your engine produce power. These small electrical devices create an arc of electricity across two leads that are not touching but are close enough together that electricity can jump the gap between them.
The benefits of changing spark plugs include an increase in overall engine performance. Below is a list of the benefits included
- Better combustion
- Improve fuel efficiency
- Consistent combustion
- Enjoyable drive comfort
- Smooth running engine

Conclusion
Spark plugs are a crucial part of an engine. They are used to ignite the fuel/air mixture in the combustion chamber, which is then ignited by the spark plug.
If you have a car with a failing spark plug, it may cause your car to misfire and not start. This can be caused by many factors such as a faulty connection between the coil and spark plugs, worn out or cracked piston rings that prevent fuel from reaching the combustion chamber, or air leaking into the combustion chamber.
Symptoms of failing spark plugs: engine won’t start, car misfires and may not run smoothly, check engine light is on.
