Description

The NGK 4548 CR9EK is a standard OE-style nickel spark plug featuring a dual (multi-ground) electrode design for enhanced durability and consistent ignition. Built with NGK’s proven “yellow box” technology, it delivers reliable performance in high-revving engines, especially in motorcycles and powersports applications.

Its copper core ensures excellent heat dissipation, while the dual ground electrodes extend service life by reducing electrode wear. Designed for OE applications, this plug provides stable combustion, smoother operation, and dependable starts.

Key Features

  • Multi-ground (dual electrode) design for extended service life
  • OE-equivalent nickel center electrode for reliable ignition
  • 98% pure copper core for superior heat transfer
  • 5k Ohm resistor reduces electrical interference
  • Trivalent metal plating for corrosion and anti-seize protection
  • High-grade ceramic insulator for durability and heat control
  • Ideal for high-performance and high-revving engines
