Niterra 4495 V-Power Nickel Spark Plug BPZ8H-N-10

The Niterra 4495 (BPZ8H-N-10) is a V-Power nickel spark plug designed for reliable performance in marine and powersports applications. This spark plug features NGK's signature V-Power technology with a unique v-cut center electrode that directs the spark to the edge, helping it develop more rapidly for improved ignitability and reduced quenching.

Key Features:

• V-cut nickel alloy center electrode increases ignitability for quicker starts and smoother idle
• 98% pure copper core provides superior heat dissipation and conductivity
• High-grade alumina silicate ceramic insulator for optimal dielectric performance
• Trivalent metal plating ensures superior anti-corrosion and anti-seizing properties
• Cold-rolled threads prevent cross-threading and damage to cylinder heads
• Preset gap of 0.040 inches (1mm) for easy installation
• M14 thread size with 0.500 inch reach
• Heat range 8 with 13/16 inch hex size

This OE-quality spark plug is commonly used in Mercury, Mariner, Nissan, Suzuki, and Tohatsu outboard engines. The resistor-type design with standard J-gap ground configuration provides consistent performance and reduced electromagnetic interference. Best suited for applications originally equipped with nickel alloy plugs.
