NGK 6799 LZKAR7A Standard Nickel Spark Plug, 12mm, Heat Range 7, Resistor

The NGK 6799 (LZKAR7A) Standard spark plug is a traditional nickel alloy, copper core resistor spark plug built to OE specifications. It is a standard replacement for engines that came with nickel alloy plugs from the factory. It is also sold under the NGK stock number 6799 and the service number LZKAR7A.

Key Features:

• Solid 98% pure copper core for heat dissipation, conductivity and a wide heat range
• Nickel alloy center and ground electrodes for consistent OE-style performance
• High-grade alumina silicate ceramic insulator for strong dielectric performance and heat transfer
• Cold-rolled threads help prevent cross-threading and cylinder head damage
• Trivalent metal plating resists corrosion and seizing, which makes installation and removal easier
• Triple gasket sealing helps prevent combustion gas leakage
• Built-in resistor helps suppress radio frequency interference
