What Are the Different Types of Spark Plugs


Spark plugs are a component of your car's ignition system. They are responsible for igniting the fuel-air mixture in the engine's combustion chamber, providing the power that drives your vehicle. When it comes to spark plugs, there are several different types available on the market, each with its own unique properties and advantages. Here are some of them:

Copper Spark Plugs

Copper spark plugs are the most basic type of spark plugs available on the market. They are made with a copper core that provides excellent thermal conductivity and good electrical conductivity. Copper spark plugs are generally less expensive than other types, but they have a shorter lifespan and need to be replaced more frequently. They are a good option for drivers on a budget who are looking for an affordable, reliable spark plug.

Iridium Spark Plugs

Iridium spark plugs are a more advanced type of spark plug that is made with an iridium tip. This tip is much harder and more durable than the copper core used in copper spark plugs, giving iridium spark plugs a longer lifespan. They also have better performance, providing a stronger and more consistent spark, resulting in better fuel efficiency and engine performance. Iridium spark plugs are more costly than copper spark plugs, but their durability and performance make them a popular choice for many motorists.

Platinum Spark Plugs

Platinum spark plugs are another type of advanced spark plug that features a platinum tip. Platinum is even harder and more durable than iridium, which means that platinum spark plugs have an even longer lifespan. They also have excellent performance, providing a strong and consistent spark that improves fuel efficiency and engine performance. Platinum spark plugs are the most expensive type of spark plug, but their longevity and performance make them a worthwhile buy for many drivers.

Double Platinum Spark Plugs

Double platinum spark plugs are similar to platinum spark plugs, but they feature a platinum tip on both the center and ground electrodes. This design provides even better performance and longevity than standard platinum spark plugs, making them an excellent choice for drivers who want the best spark plug for their vehicles.
