NGK BUR9EQ Spark Plug – Stock No. 5483
The NGK BUR9EQ is a cold heat range, long-reach spark plug with four ground electrodes. It is built for reliable ignition under high load and high temperature. The resistor design helps reduce electrical noise in the car’s electronics. The quad-electrode layout gives a consistent spark path and extends service life compared to a single-electrode plug.
This plug suits engines that specify NGK BUR9EQ from the factory or in performance setups that call for a 14 mm, 19 mm reach, gasket-seat plug with multiple ground electrodes. Please use the vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.
- Cold heat range (9) for high performance or high-temperature running
- Quad ground electrodes for stable ignition and longer life
- Resistor type reduces radio interference and protects sensitive electronics
