NGK SPARK PLUG DPR8Z 4730
NGK SPARK PLUG DPR8Z 4730. NGK's wide heat range results from using copper wire instead of iron cores. Copper dissipates heat quickly, cooling the electrode and insulator tip. Raised pre-ignition rating with high-conduction copper and a long nose insulator. Meets the requirements of high-performance engines. Heat Range: 8, Thread Size: 12 mm, Type: Resistor, Units: Each, Weight: 0.12 lbs, Reach: 19mm (3/4"), Hex Size: 11/16" (18mm), Seat Type: Gasket, Gap: .028" (0.7mm), Terminal Type: Stud Terminal Threads. Extended metal shell with an oversized (2.9mm) center electrode. Extended projected tip for better performance. Triple-sealed and copper-cored 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. Alternate/OEM Part Numbers: 4730, DPR8Z. Part No.: 37-DPR8Z. Does not include terminal nut.

FULL DESCRIPTION
NGK Special Spark Plug DPR8Z
This NGK spark plug is designed for high-performance engines and features a wide heat range due to its copper core construction. Copper dissipates heat more effectively than iron, helping to cool the electrode and insulator tip, which contributes to a higher pre-ignition rating.
Key Features:
- Wide heat range
- Copper core for rapid heat dissipation
- High-conduction copper and long nose insulator for increased pre-ignition rating
- Meets the requirements of high-performance engines
- Extended metal shell with an oversized center electrode
- Extended projected tip for improved performance
- Triple-sealed construction with a copper core to manage heat and prevent internal leakage
- Corrugated ribs designed to prevent flashover
- Pure alumina silicate ceramic insulator for enhanced strength and heat transfer
