Spark Plug Buying Guide

Although this engine component looks small and inexpensive, the spark plug is an extremely important part and parcel of your vehicles' engine. The internal combustion of your engine depends largely on your spark plugs. Just as its name, the spark plugs create the sparks that ignite the fuel and commence combustion.

Therefore, if you have a bad or faulty spark plug, you will most definitely have an unpleasant driving experience. The smooth movement and acceleration of your vehicle will be affected when your spark plug is faulty.

How does the Spark plug work?

Your vehicles' engine operates on a simple principle that works by capturing the energy released by tiny explosions. These explosions are created inside the cylinders by the ignition formed from the mixture of gasoline and air. In operation, deep within your engine, fuel and air come in, and they get compressed by the pistons, after which they get ignited multiple times per second. This scenario creates an energy-dense explosion that is responsible for producing the power that drives the vehicle.

The spark plug triggers this explosion, which we are talking about here. The explosion occurs when the current flows towards the center and ground electrode. This flow then creates a tiny spark. Most times, your spark plug wears down over time. The wear out can reduce your engines' fuel economy, cause drag in your engine's performance, and will inadvertently cause damage to other parts.

Therefore, paying close attention to your spark plug and changing it over time, especially when a fault appears, is cardinal. Your spark plugs may be either worn out, dirty and simply due for a change to ensure better performance. A failure to effectively do this will mean your engine will suffer dearly. Furthermore, when it comes to making the right choice of spark plug for your engine, you must understand the Spark plugs' construction in a general sense.
