What Is a Spark Plug?
A spark plug is a pair of electrodes and is an important component which is essential to the running of your car engine and it works by delivering electric current from the ignition system of the car to the combustion chamber. The electric spark that is produced kindles the mixture of fuel and compressed air and powers the car engine.
Every time a spark is produced by the spark plug, a tiny amount of metal is eroded from the plug and over time with use, a gap is formed between the spark plugs which hampers the sparking efficiency and the car begins to run rough, misfires and starts to consume excess fuel; and, eventually the “check engine” light starts flashing.
So, when your car begins to display all these signs, the solution is extremely simple. All you need to do is replace the spark plug and it is so simple that you can do it on your own without having to take your car to the service station. Typically, car manufacturers and mechanics recommend that you replace the spark plug every 25,000 to 40,000 miles run by the car.
Making use of high-quality spark plugs ensures that your car gives the best performance and runs efficiently.
Types of Spark Plugs
There are essentially 4 kinds of spark plugs available:
- Copper core
- Double platinum
Copper Core Spark Plugs
These are the most inexpensive variety of spark plugs. Copper core spark plugs work at much higher temperatures when compared to the other varieties and are very good conductors. You can expect the copper spark plugs to last around 20,000 to 40,000 miles.
Iridium Spark Plugs
The spark plugs made of iridium are less conductive and they work at much lower temperatures. Typically, iridium spark plugs last for around 40,000-60,000 miles, but they are prone to get overheated. However, in terms of performance, they offer quite a lot before they need to be replaced.
Platinum and Double Platinum Spark Plugs
Platinum spark plugs are higher in quality when compared to iridium ones and last around 40,000-80,000 miles. Double platinum spark plugs are improved versions compared to the single plated platinum spark plugs. Although these spark plugs are not the best conductors, they are the best in term of the quality and have a longer lifespan and offer enhanced engine performance.
Finding the Right Spark Plug for Your Car
Here are some factors that you must evaluate before deciding on the right ones for your car.
Knowing Your Vehicle Information
You must know the details of your car as this will help you buy the right kind and size of spark plugs. Information such as the year of manufacture, model and make, engine size or displacement, fuel injection type and the number of cylinders is required. This information can be found on your car’s registration card. Your car manual will also give you specific details of the type of spark plugs you should buy for your vehicle. You not only can get the size of spark plugs required, it will also probably suggest the brand of spark plugs required.
You should buy spark plugs of high-quality and not try and save money by cutting corners. Buying good quality spark plugs can help you save quite a bit of money in the long term. In fact, you will be able to save significantly more amount of money than you would by saving on buying cheaper spark plugs. Also, a high-quality spark plug can save you money on fuel consumption in the long run.
You can determine that a spark plug is of high-quality by looking at the materials and the design features of the spark plug. For several years, copper core spark plugs were the ones that most people used; however, today, you have better quality spark plugs made of other superior materials such as double platinum, platinum and iridium that will enable your car to run more smoothly for a longer time.
Other things that determine that the spark plug is of higher quality are things like the grooves that cut into the electrodes or the spark plug seals which are specially designed to control the flashover when the spark plug is fired up.
When you buy a spark plug for your car, consider the main purpose for which your vehicle is used. Spark plugs used in high-performance sports cars that you use occasionally on the weekends are quite different compared to the ones used in standard cars that you use for your daily commuting to work and for other jobs.
Deciding on the kind of spark plugs for your car can be quite challenging, especially given the number of options available. We have reviewed some of the best spark plugs and compiled a list of some of the best spark plugs you can consider for your car.
