Description

As their name suggests, spark plugs are the spark of electricity that ignites the combustion needed to start your vehicle. Spark plugs emit a bolt of electricity across a small gap igniting the fuel and air mixture that puts the pistons in motion and gets your vehicle up and running.

 

It’s a crucial job that spark plugs have because if they’re worn out they won’t emit a spark and start your engine or can even cause significant damage. It’s not just a bad battery that could be keeping your vehicle from turning over — it could be the spark plugs.

 

Spark plugs are crucial to the health of your vehicle’s engine and car, but how often should you be replacing them? Well, there’s obviously a lot of variables when it comes to how quickly your spark plugs go through enough wear-and-tear to the point where a replacement is necessary.

 

 

 

Questions and Answers

How Often Should I Replace My Spark Plugs?
A modern model with spark plugs that are platinum-made should last at least 50,000 miles while iridium spark plugs are good for up to 100,000 miles and sometimes more. Consult your owner's manual to learn what kind of spark plugs your model has and the recommended lifespan of them. If you notice some problems before either benchmark then it's always better to replace them sooner rather than later to avoid getting stranded as well as potential damage to the vehicle.
How Do I Know I Need to Replace My Spark Plugs?
How can car owners know it's time to replace their spark plugs? There are a few key giveaways car owners will notice when their spark plugs begin to go bad. If the vehicle struggles to start, the problem may be worn spark plugs. While driving, if you notice a rough idle, sluggish acceleration, or an increased fuel consumption, it may be time to replace worn out spark plugs. Regardless, you should check or have your spark plugs inspected regularly even if you haven't noticed any problems.
What Causes Spark Plugs to Go Bad?
The last bit of info we'll leave drivers with is what causes spark plugs to go bad. Are there ways drivers can avoid wear-and-tear on their spark plugs? The most common problem with spark plugs is the build up oil and carbon that dulls their effectiveness. Now, some of this is unavoidable and the natural course of a vehicle's life, but things like the overheating of spark plugs from an incorrect fuel-to-air ratio can wear out spark plugs faster. Other factors for accelerated spark plug degradation include poor fuel quality and a bad fuel filter that can lead to a carbon build up. Another thing for drivers to look out for when their spark plugs are causing problems is a loose wire connection from low-quality plugs or improper engine tuning. Drivers should keep an eye on these things to help prolong the use and life of their spark plugs.
