NGK SPARK PLUG DPR9Z 4830

NGK Special Spark Plug DPR9Z

This NGK spark plug features a half-threaded design and is engineered for high performance. Its construction includes a copper core and triple-sealed elements to ensure optimal heat removal and prevent internal leakage. The corrugated ribs are designed to prevent flashover, while the pure alumina silicate ceramic insulator provides superior strength and heat transfer capabilities. An extended metal shell with an oversized center electrode and a projected tip enhance performance.

Key Features:

• Wide heat range achieved through a copper core, which dissipates heat more quickly than iron cores.
• Raised pre-ignition rating due to high-conduction copper and a long-nose insulator.
• Meets the requirements of high-performance engines.
• Extended projected tip for improved performance.
• Triple-sealed construction for optimal heat removal and prevention of interior leakage.
• Corrugated ribs prevent flashover.
• Constructed with pure alumina silicate ceramic insulator for greater strength and better heat transfer.
• Extended metal shell with an oversized 2.9mm center electrode.
• Sold individually.
