One of the most racing spark plugs from NGK! Depending on your configuration and weather conditions, the B10 spark plugs may be too hot and the B11 may turn out to be too cold. It is for this reason that the thermal rank 105 racing spark plug exists! It is used extensively on a lot of competition engines because the 105 rank is very helpful. This model is the R6252E-105 with resistance so do not forget to tune it with a specific anti-parasite comprising a resistance (5kΩ). It offers outstanding power and ignition. It clogs very little and rarely burns thanks to its materials. It will be able to accept the highest regimes. However, remember to install it only once correctly adjusted because if you install it being too rich or poor carburetion level, in a very short time it will be in poor condition and will bring you risks of burning the spark plug, tightening, drilling piston ...
