Platinum vs Iridium Spark Plugs: Which is Better for You?

Understanding Spark Plugs: A Brief Overview

Spark plugs are critical components in the internal combustion engine, acting as the ignition system's centerpiece. Their primary function is to initiate the combustion process by generating a spark that ignites the air-fuel mixture within the engine's cylinders. This ignition is essential for the engine to produce power, making spark plugs vital for vehicle performance.

Key Functions of Spark Plugs

• Ignition: The most prominent function of a spark plug is to create a spark that ignites the fuel-air mixture, enabling engine operation.
• Heat Management: Spark plugs dissipate heat from the combustion process, helping to maintain the engine's optimal operating temperature.
• Fuel Efficiency: A well-functioning spark plug can enhance fuel efficiency by ensuring the fuel is burned completely.
• Emissions Control: Proper operation of spark plugs minimizes harmful emissions by promoting efficient combustion.

There are various types of spark plugs, each designed to work optimally under specific conditions. These include standard copper spark plugs, platinum spark plugs, and iridium spark plugs. The choice of spark plug can significantly affect your engine's performance, lifespan, and maintenance needs.

Types of Spark Plugs

• Copper Spark Plugs: Known for their good conductivity, these plugs are typically less expensive but have a shorter lifespan.
