Superior Ignition with Brisk Iridium Performance

The Brisk Iridium Performance RR14BYIR-7 spark plug is designed for enthusiasts who demand longevity and consistent ignition performance. Built with a 14mm thread and 25mm reach, this iridium-enhanced plug offers exceptional resistance to wear and erosion, making it an ideal choice for high-output engines that see both street and track use. The fine-wire iridium center electrode requires less voltage to fire, ensuring a stable spark even under high load conditions.

Key Features

  • Thread Size: 14mm
  • Reach: 25mm
  • Heat Range: 14
  • Seat Type: Tapered
  • Resistor: Included

By optimizing the flame kernel development, the RR14BYIR-7 improves combustion efficiency, leading to smoother idling and better throttle response. The iridium alloy construction provides a significantly longer service life compared to standard plugs, reducing maintenance intervals without sacrificing power. This plug is perfect for modern engines that require precise ignition timing and reliable performance under varying temperatures. Its tapered seat design guarantees a perfect seal, preventing compression loss during high-boost or high-compression operation. If you are looking to balance durability with performance, this iridium plug is the ultimate solution for your vehicle. Discover the full range of ignition solutions at GGCRACING.
