Product Description

The NGK 1406 Laser Iridium High Ignitability Spark Plug (service code **DILKAR7B11**) is engineered to deliver reliable ignition performance and long service life in modern Nissan and Infiniti petrol engines. Featuring a laser-welded iridium center electrode and dual fine platinum ground electrode, this plug offers superior ignitability, improved combustion efficiency, and extended durability compared with conventional plugs. Its copper core enhances heat dissipation, while the built-in resistor helps suppress electrical interference for smooth engine operation.

Fitments confirmed across multiple trusted parts sources include a broad range of **Nissan and Infiniti vehicles** - from **sports coupes like the 350Z**, sedans such as the **Altima and Maxima**, to larger SUVs and trucks like the **Pathfinder, Armada, Titan, NV2500/NV3500, and QX series**. This makes NGK 1406 ideal for maintenance intervals where OE-equivalent spark plugs are required. Always follow your vehicle's service manual for correct torque and gap specs when installing new plugs.
