They are the unsung heroes of your engine, responsible for igniting the air-fuel mixture in your engine's cylinders. This controlled explosion is what provides the power to get your car moving. Without a good spark, your engine is just a collection of metal parts – no go! So, in essence, spark plugs create the spark that starts the combustion process. It's a pretty critical job, wouldn't you say?

Now, there are different types of spark plugs out there, each with its own pros and cons. But, generally, they all do the same basic thing: provide a spark. However, the materials they're made of and the design can make a massive difference in their performance and how long they last. That's where materials like iridium come into play. It's time to know about how the spark plug works. When the engine is running, the spark plug receives a high-voltage electrical charge from the ignition system. This electricity jumps across a gap between the center electrode and the ground electrode, creating a spark. This spark ignites the air-fuel mixture, causing a controlled explosion that pushes the piston down, which, in turn, powers your vehicle. The efficiency and reliability of this spark are crucial for optimal engine performance, fuel economy, and emissions. Therefore, keeping your spark plugs in top shape is key to engine health.

Over time, spark plugs wear down due to the intense heat, pressure, and electrical arcing they endure. This wear can lead to various problems, such as misfires, reduced fuel efficiency, and even engine damage. The lifespan of a spark plug is influenced by several factors, including the type of spark plug, the engine's design, and the conditions under which the vehicle is operated.
