Double Platinum Spark Plug: Enhanced Durability & Longer Service Life is engineered for peak performance and reliability. Featuring a platinum-to-platinum design, it minimizes gap erosion and reduces misfires, ensuring extended durability and a longer service life. The yttrium-enhanced ground electrode optimizes heat transfer, making it highly resistant to extreme temperatures and pressure, while the high alumina ceramic insulator provides superior thermal conductivity and dielectric strength. Its multi-rib insulator prevents flash-over, enhancing overall efficiency. Designed with an extra-long projection center electrode and platinum tips on both the center and ground electrodes, this spark plug delivers exceptional performance for distributor-less ignition system (DIS) engines. With a tapered seat type and built-in resistor, it offers a reliable fit and consistent ignition. Perfect for those seeking a performance-grade solution, this spark plug outshines copper and standard platinum plugs, making it a valuable upgrade for your engine's ignition system.
