The NGK BR6ES is a high-quality standard spark plug with a nickel electrode and built-in resistor, designed for a wide range of older cars and motorcycles, such as Honda Accord I (1976–1981), BMW 2002 (1968–1975), and Triumph Bonneville T120 (1959–1975). It is suitable for 4-stroke gasoline engines, providing reliable ignition, stable performance, and a long lifespan. Equipped with a 5 kΩ resistor, it reduces electromagnetic interference, which is beneficial for vehicles with basic electronic systems. This spark plug is ideal for classic models like Fiat 124 Spider or Moto Guzzi V7, where its robust nickel electrode and triple sealing system prevent gas leakage and ensure durability. Manufactured to strict NGK standards, with a high-quality aluminum silicate insulator, it offers good heat transfer and corrosion resistance.
