NGK BCP7ET Spark Plug – Triple Electrode (Stock No. 2078)
The NGK BCP7ET is a robust, triple-ground-electrode spark plug designed for reliable ignition under hard use. It uses a projected tip and a slightly colder NGK heat range 7, making it a solid choice for sustained high-load driving or mildly tuned engines that run hotter than stock.
Triple electrodes help maintain a strong spark as the plug wears. The design also resists fouling and supports smooth cold starts. This is a standard nickel plug, built for durability and consistent performance rather than outright power gains.
- Good for sustained spirited driving where a colder plug is preferred
- Triple ground electrodes for stable spark and longer service life
- Projected tip for improved cold starting and combustion
Note: This plug is non-resistor. Check your vehicle’s requirements before choosing a non-resistor plug. For exact fitment, use the vehicle lookup or see the Vehicle Fitment tab.
