NGK 94806 LTR6BP13 Laser Platinum Spark Plug

The NGK 94806 Laser Platinum spark plug (NGK part number LTR6BP13) is an OE-equivalent replacement plug. It is also called a platinum spark plug or double platinum ignition plug. It has a laser-welded platinum center electrode tip and a platinum disc on the ground electrode. This construction resists corrosion and erosion, so the plug lasts longer and runs reliably. It suits distributorless ignition systems (DIS) "waste spark" setups that call for double precious metal plugs.

Key Features:

• Laser-welded platinum center electrode tip and platinum ground electrode disc
• Alumina silicate ceramic insulator for strength and better heat transfer
• Copper core to help remove heat
• Trivalent metal plating resists corrosion and seizing
• Corrugated insulator ribs help prevent flashover
• Triple-seal construction helps prevent leakage through the shell
• Cold-rolled threads for easier installation and removal
• Resistor type for reduced radio interference
