Most newer vehicles have a check engine warning light that will come on if misfires are present after three or four consecutive starts. Worn spark plugs can create rough engine idling, misfires, hard engine starts, reduced power, and the consumption of higher fuel. Keep an eye out for warning signs that spark plugs are at the end of their life. Even if the recommended mileage has not been reached, you should pay close attention to how your car is running. If it’s been a good amount of time since you have changed your spark plugs, they are probably in worse shape than you think. Also, if the engine starts to wear, it will allow oil into the combustion chamber which will cause spark plugs to become fouled up by the oil. During short trips when engine temperatures are low can lead to foul-ups of spark plugs due to a build-up of carbon on the tips. All these factors take a toll on the life of spark plugs. In reality, improper combustion can cause excessive ethanol mixed in by petrol stations, incorrect air/fuel mixtures, cold weather conditions, too low octane fuel, or other issues. The lifespan for spark plugs is based on the assumption that these plugs are in top tune and experiencing ideal running conditions during the entire period of their life.
As the coating wears down, the gap between the centre electrode and the ground electrode will get wider which, in turn, reduces the effect of the spark. It doesn’t matter which metal is used to coat the spark plug tips, it will gradually wear out over time as the engine is driven. Many newer vehicles feature one coil for each cylinder, the older model of cars rely on a single coil connected to an ignition distributor which feeds the spark plugs through a set of spark plug wires. The centre electrode receives its power through an ignition coil. The metal used to coat the tip of the ground electrode depends on the different types of spark plugs including nickel, platinum, copper, double platinum, silver, and iridium. Electricity travels between these two points whenever the spark plug fires. The distance between these two points is referred to as a gap. There is another metal piece called a ground electrode which protrudes from the bottom of the threaded area, then curves around and stops directly under the centre electrode.
This core is known as the centre electrode or just electrode. How Spark Plugs OperateĪll spark plugs are designed with an exterior shell that covers an inner central core made of metal. We’ll start by understanding how spark plugs operate and how they wear out. The intervals include 30k, 60k, 100k, and 120k miles. In this article, we will address commonly asked questions such as how often do you need to replace your spark plugs? We will look at ten of the best-selling vehicles over the past few years and show a range of recommendations for changing spark plugs based on the type of plugs chosen by engineers. Over time, your engine will take a toll on spark plugs. As it’s a known fact that lightning bolts are destructive in nature, you should consider these miniature bolts going off in your engine. The best way to describe this action of spark plugs firing off is similar to a miniature bolt of lightning.
