Features:
- Trivalent Metal Plating: Offers unparalleled anti-corrosion and anti-seizing properties, ensuring easy installation and removal while providing long-term protection against the elements.
- Corrugated Ribs: Intelligently designed to prevent "flashover," a phenomenon where electrical energy bypasses the electrode. This ensures the full voltage is directed to the spark gap for the strongest possible spark.
- Pure Alumina Silicate Ceramic Insulator: Provides superior physical strength and exceptional heat transfer, protecting against electrical leakage and maintaining structural integrity even under extreme thermal stress.
- Copper Core: Aids in the rapid removal of heat from the firing tip, extending the spark plug´s thermal range and protecting the engine against damaging pre-ignition and detonation.
- Triple Seals: A robust internal sealing process prevents combustion gas leakage, maintaining optimal engine compression and ensuring the spark plug performs flawlessly throughout its service life.
