How Long Do Iridium Spark Plugs Last?

Usually, iridium star plugs last longer than other star plugs. Though they last a long time, it doesn't mean they will last a lifetime. If your engine doesn't have any problem, then the iridium star plug should work for 100,000 to 120,000 miles.

Conventional star plugs can last up to 20,000 to 30,000 miles. However, you should change the star plug if you face any difficulty earlier.

How Often Should You Change Star Plugs?

When you are using "extended life" spark plugs, it will cost you more but give you a better performance. These kinds of spark plugs can run about 100,000 miles. When the spark plug comes to the end of its lifespan, the gap inside it will slowly increase. This will result in the malfunctioning of the car engine.

Star plugs don't need to change frequently. You can change the spark plug when it has completed 100,000 miles. Occasionally, you may have to change it before the anticipated time. But you should know the signs when to change the spark plugs. Let's move on to the signs you should consider.

Signs That Indicate Something is Wrong with Your Star Plug

Some of the common red flags that your vehicle will show if it has any problem are discussed below in detail.

Reduced Fuel Efficiency

When the spark plug is in good health, it will burn fuel efficiently. The fuel is burned in the combustion cycle. As it runs efficiently, it gives you a chance to save your money because you will need less gas for an efficiently running spark plug than a faulty one.

When the spark plug is not running optimally, it may have a gap between its electrodes. It's best to take them off and examine them closely. The gap between the electrodes can be far or close. You don't have to replace the whole spark plug in this case. You can adjust the gap as the factory settings. Doing this step can spare you the hassle of buying a new spark plug.

Reduced Acceleration of Vehicle

Most of the reason for poor acceleration comes from the vehicle's ignition system. Because of the modern and advanced engines, it's easy to sense any problem. These engines tell the onboard computer and the ignition system to send electric pulses. These electric pulses help ignite the spark plug so, if you see any problem in acceleration, then it's because of a faulty spark plug.

A simple solution for this problem is to change the faulty spark plug. A spark plug is designed in such a way that its materials create a hot spark. This spark fires off the fuel. In this process, the spark plug can wear out in a short time.

When the spark plug wears out, the efficiency degrades. This is how the acceleration problem occurs. When you notice your vehicle is not acting as before in acceleration, it's time to contact your mechanic for a checkup.

Difficulty in Starting the Vehicle

Heading towards your destination, and suddenly your vehicle isn't taking a start? People often assume that the reason for the car not starting is the problem with the battery. This assumption can be wrong if it's the spark plug that's causing the problem. When spark plugs get worn out, it gets clogged, and the engine needs to work hard to start the vehicle.

Engine Malfunctioning

There are several reasons for the engine to malfunction, like low-quality ignition coil or low-quality fuel. One of the reasons for engine misfire can be a be spark plug. You can identify the problem when the engine suddenly losses its pace and starts fine again. The engine will also make light explosive sounds when the spark plug is not working well.

Your Car Is Giving A Signal

Even if you forget to check your car regularly, the vehicle will give you a signal. When "check engine" light is turned on automatically, then, of course, it's time for a checkup. Modern-day cars are designed so cleverly that it can alert you to any potential problem.
