Want to keep your engine running smoothly? Here's what makes up a spark plug and how it works: 🔹 Terminal: Connects to the ignition system for spark delivery. 🔹 Insulator: Prevents electrical short-circuiting and insulates high voltage. 🔹 Center Electrode: Delivers the spark that ignites the air-fuel mixture. 🔹 Ground Electrode: Completes the circuit, ensuring ignition. 🔹 Electrode Gap: The gap where the spark forms, essential for efficient ignition. 🔹 Shell: The metal casing that holds the components together. 🔹 Gasket & Sealing Ring: Prevent leaks and ensure proper sealing. 🔹 Heat Range: Helps the spark plug dissipate heat properly for optimal performance.
