NGK 93427 BPR8ES-6 Standard Nickel Spark Plug, 14mm Thread, Heat Range 8

The NGK 93427 (BPR8ES-6) Standard Spark Plug is a resistor-type nickel spark plug built for dependable ignition in automotive, powersports and small engine applications. It is a direct-replacement plug that is pre-gapped at 0.024 in (0.6 mm) and uses NGK's proven standard design with a copper core.

Key Features:

• Solid copper core improves heat dissipation, conductivity and heat range
• Trivalent metal plating resists corrosion and seizing, which makes installation and removal easier
• Cold-rolled threads help prevent cross-threading and cylinder head damage
• Pure alumina silicate ceramic insulator adds strength and improves heat transfer
• Corrugated insulator ribs help prevent spark flashover
• Triple-seal construction helps prevent combustion gas leakage
• Built-in 5k ohm resistor helps suppress ignition noise
