When it comes to high-performance engines, spark plugs play a crucial role in ensuring optimal engine efficiency, power output, and longevity. With numerous materials available, selecting the right spark plug can be a daunting task, especially for those who are not familiar with the intricacies of engine technology. In this article, we will delve into the world of spark plugs, specifically comparing iridium spark plugs with platinum spark plugs. Are iridium spark plugs better than platinum? Let’s explore the differences and similarities between these two materials to make an informed decision.
What are Spark Plugs?
Spark plugs are a critical component of an internal combustion engine, responsible for igniting the fuel-air mixture inside the engine’s cylinders. They consist of a metal body, a ceramic insulator, and a metal electrode. When the engine is running, the spark plug receives a high voltage from the ignition coil, creating a spark that ignites the fuel-air mixture, allowing the engine to run efficiently.
What are the Key Differences Between Iridium and Platinum Spark Plugs?
Iridium and platinum spark plugs are both high-performance materials used in spark plugs. However, they have distinct differences in terms of their composition, durability, and performance.
Composition
Iridium spark plugs are made from iridium, a rare and highly conductive metal. Iridium is known for its exceptional hardness and resistance to wear and tear. Platinum spark plugs, on the other hand, are made from platinum, a dense and highly conductive metal. Platinum is also known for its durability and resistance to corrosion.
Durability
Iridium spark plugs are more durable than platinum spark plugs due to their exceptional hardness. Iridium is resistant to wear and tear, which means it can withstand the high temperatures and pressures inside the engine without degrading. Platinum spark plugs, while durable, are not as resistant to wear and tear as iridium spark plugs. (See Also: How Often Should You Check Your Snowmobile Spark Plugs? For Peak Performance)
