NGK BUR6ET Spark Plug – Triple Ground, Resistor, 14 mm Thread
The NGK BUR6ET is a reliable, long-life spark plug designed for clean ignition in everyday and performance road use. It uses three ground electrodes to keep the spark path stable as the plug wears. This helps maintain smooth idle, better cold starts, and consistent throttle response over more miles.
Its projected tip places the spark deeper in the combustion chamber for efficient burn, while the built-in resistor reduces electrical noise that can affect the radio or ECU. The standard nickel centre electrode offers solid performance and good value.
- Triple ground electrodes for stable spark and longer service life
- Projected tip for cleaner combustion and smoother running
- Resistor design to cut electrical interference
Important: The gap is factory set. Do not bend the multiple ground electrodes. Always follow the correct torque when fitting.
