NGK Racing B9 EG long base spark plug nickel competition (average cold index)

A competition spark plug from NGK racing, the B9 EG is an excellent compromise between the B9 ES and the BR10 EGV. This model is designed / typed competition and has a nickel electrode. It will be able to accept the highest regimes. However, remember to install it only once correctly adjusted because like a B9 EVX, if you install it being too rich or poor fuel level, in a very short time it will be in poor condition and will bring you the risk of burning the spark plug, clamping, piston drilling ...
