NGK Racing R7376-10 competition long base spark plug (very cold index)

One of the most racing spark plugs from NGK! Depending on your configuration and weather conditions, the B9 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 10 racing spark plug exists! It is widely used on many competition engines because its thermal rank is very helpful. This model is the R7376-10 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 and its iridium electrode. It will accept the highest revs without any difficulty. However, remember to install it only once correctly adjusted because if you install it while being too rich or poor fuel level, in a very short time it will be in poor condition and will bring you risk of burning the candle, tightening, piston drilling…! Supplied with its olive.
