NGK Nickel Spark Plug (DF8H-11B)

When it's time to replace the spark plugs on your Infiniti or Nissan, NGK's Laser Iridium High Ignitability plugs are a solid choice. These are designed to be direct OE replacements, meaning they're built to the same standards as the plugs that came with your car. They help ensure your engine runs smoothly and efficiently, providing reliable starts and consistent power delivery.

What sets these plugs apart is the iridium-tipped center electrode, which is significantly harder than platinum, offering extended durability. The pure alumina ceramic insulator helps manage heat effectively, preventing the plug from overheating, while the copper core also aids in heat removal. You'll also find a raised platinum pad on the ground electrode, which helps with even wear, especially in modern distributorless ignition systems, and contributes to a stronger spark. The trivalent metal plating on the body helps prevent corrosion and makes them easier to remove down the road.

This box contains four plugs, suitable for many V6 applications. They are recommended for vehicles that originally came with OE DFE iridium alloy plugs, ensuring compatibility and optimal performance.
