Product Details

The NGK 4730 (DPR8Z) Standard spark plug is a resistor-type nickel spark plug built to OE specifications. It is a dependable replacement ignition plug for motorcycles, powersports and small-engine applications. NGK is a leading OE spark plug supplier, and Standard plugs have been an OE cornerstone for decades.

Key Features:

  • Solid copper core for heat dissipation, conductivity and a wide heat range
  • Nickel-alloy center and ground electrodes
  • Built-in 5k ohm resistor to suppress ignition noise and radio interference
  • High-grade alumina silicate ceramic insulator for dielectric strength
  • Triple gasket sealing to prevent combustion gas leakage
  • Cold-rolled threads to help prevent cross-threading and cylinder head damage
  • Corrosion-resistant plating for easier installation and removal

Specifications:

  • NGK part number: 4730 (service number DPR8Z)
  • Heat range: 8
  • Thread size: M12 x 1.25 (12 mm)
  • Reach: 19 mm (0.750 in)

  • Pre-set gap: 0.028 in (0.7 mm)
  • Terminal: Stud
  • Ground electrode: Single J-gap design

This plug suits engines that originally came with nickel-alloy plugs. It is not recommended for engines fitted with factory precious-metal plugs. For longer service life, NGK offers iridium plug upgrades.
