The BR9ECS candle from NGK is a very solid original type candle with a long base. Use it during your running-in and your settings, quite cold, it has the right temperature in order to carry out the settings and running-in or to run your original or pushed engine all the time. It is not made for extreme performance but will be able to resist a large kit without problems, unlike a standard B9, this one is equipped with a mass electrode of oblique type as well as a resistance. It must therefore be accompanied with a resistive anti-parasite 5kΩ. Pattern with olive. 
What does BR9ECS mean:
B = Ø14mm base (to be tightened with a 20.8mm key)
R = With resistance of 5 kOhm
9 = average thermal index
E = thread length 19.00mm
CS = Oblique mass electrode of compact type (insulator length: 18.5mm)
