Product Details

The NGK GR4 V-Power spark plug delivers reliable ignition performance for a wide range of automotive applications. Engineered with NGK's proven V-Power technology, this spark plug features a unique V-groove center electrode that directs the spark to the edge of the electrode, improving ignitability and reducing quenching for more complete combustion.

Key Features:

  • V-groove center electrode design concentrates spark energy for faster flame kernel development
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Cold-rolled threads prevent cross-threading and damage to cylinder heads
  • Triple gasket seal eliminates combustion gas leakage
  • High-grade alumina silicate ceramic insulator for superior strength and heat transfer
  • Copper core electrode for excellent heat dissipation and extended service life

NGK's V-Power spark plugs are designed to meet or exceed OE specifications, providing dependable performance and fuel efficiency. The GR4 is engineered for specific heat range and reach requirements, ensuring optimal combustion in compatible engines. Backed by over 80 years of spark plug manufacturing expertise, NGK remains the leading choice for automotive, motorcycle, and small engine applications.
