NGK V-Power UR4 Spark Plugs - Box of 4

Experience enhanced engine performance and reliability with the NGK V-Power UR4 Spark Plugs. Designed as a high-quality replacement for OE applications, these spark plugs offer improved ignitability and consistent performance, ensuring your engine runs smoothly and efficiently.

Key Features and Benefits:

  • Improved Ignitability: The unique V-cut in the center electrode promotes a more focused spark, leading to quicker starts and a smoother idle.
  • Durable Nickel Alloy Construction: Features a robust nickel alloy center electrode designed for longevity and reliable performance.
  • Strong Ceramic Insulator: NGK's high-grade alumina silicate ceramic provides excellent dielectric strength, preventing electrical breakdown and ensuring a strong spark.
  • Corrosion and Seizure Resistance: Trivalent metal plating on the shell offers superior protection against corrosion and makes removal easier, preventing seizure.
  • OE Equivalent Performance: Engineered to meet or exceed the performance standards of your vehicle's original equipment spark plugs.

Reliable Engine Performance

The V-Power design is specifically engineered to enhance the spark's ability to reach the air-fuel mixture, resulting in more complete combustion. This translates to better fuel economy, improved throttle response, and reduced emissions. Whether you're performing routine maintenance or addressing minor performance issues, NGK V-Power spark plugs are a trusted choice for restoring and maintaining optimal engine function.

This box contains four UR4 V-Power spark plugs, suitable for a wide range of classic and modern vehicles. Ensure your ignition system is performing at its best with NGK quality, available at GGCRACING.
