Understanding the jargon is essential when examining various spark plug kinds. Every spark plug has a top ceramic and metal terminal that attaches to a coil boot or a spark plug wire. The core of the plug is typically made of copper and features a center electrode. The remainder of the spark plug's body consists of a threaded component that screws into the engine's cylinder head and a side electrode. The "gap" that is formed between this side electrode and the center electrode is where the spark emerges. But different electrode materials are employed in plugs. Key Features: Spark Plugs that operate in a much temperature range than standard spark plugs. Both pre-ignition and carbon accumulation is away. The copper core center electrode offers more durability and accurate temperature control. Maximum corrosion resistance is secured.
