- Pure alumina silicate ceramic insulator provides superior strength and better heat transfer
- Trivalent metal plating for superior anti-corrosion and anti-seizing properties
- RECOMMENDED USAGE: Best for vehicles with OE fine wire iridium alloy plugs
- Copper core aids in heat removal
- Triple seals prevent leakage
The NGK Laser Iridium Spark Plug (Part Number 5477) offers exceptional performance and durability for a variety of vehicles including motorcycles, ATVs, and snowmobiles. Engineered specifically for OE applications, these spark plugs feature an iridium-tipped center electrode that is six times harder than platinum, ensuring a longer lifespan and consistent performance over time. The high-grade pure alumina ceramic insulator provides superior strength and efficient heat transfer, reducing the risk of overheating and ensuring reliable engine starts. The copper core aids in heat removal, maintaining optimal operating temperatures for maximum efficiency and engine longevity. Triple seals are incorporated to prevent any leakage, maintaining the integrity of the spark plug under demanding conditions.
Most NGK Laser Iridium spark plugs incorporate a platinum pad on the ground electrode for even wear and optimal performance in distributorless ignition systems. The trivalent metal plating enhances corrosion resistance and reduces seizing, which simplifies installation and replacement. These spark plugs are recommended for vehicles equipped with OE fine wire iridium alloy plugs, making them a reliable choice for riders of Arctic Cat snowmobiles, Harley-Davidson motorcycles, Buell bikes, and Arctic Cat ATVs from model years 1996 to 2009. The design and materials used in these plugs ensure efficient heat transfer, improved durability, and consistent ignition performance, making them ideal for demanding off-road and street riding conditions. Whether you require a replacement for your Arctic Cat Panther, Arctic Cat Bearcat, or Harley-Davidson touring motorcycle, these NGK Laser Iridium spark plugs are engineered to deliver outstanding ignition reliability and longevity, providing peace of mind during every ride.
