Product Details

The NGK UR4 V-Power spark plug delivers reliable ignition performance for a wide range of small engines, lawn equipment, and powersports 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-Power design with V-groove center electrode for enhanced spark performance
  • Copper core electrode for superior heat dissipation and conductivity
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Corrugated ribs on insulator prevent flashover and improve spark containment
  • Cold-rolled threads prevent cross-threading and damage to cylinder heads
  • Triple gasket seal eliminates combustion gas leakage

This 4-pack configuration (NGK stock #6630) provides convenient multi-cylinder coverage or replacement inventory. NGK spark plugs meet or exceed OEM specifications and are backed by over 80 years of ignition expertise. Ideal for lawn mowers, generators, ATVs, motorcycles, and other small engine applications requiring reliable, consistent spark performance.
