Racing Spark Plug 4216

【NGK R0045Q-10 Racing Plug 4216 ngk r0045q-10-4216】
Racing plugs recommended for two-wheeled and four-wheeled vehicles come in various types designed to further improve performance when used in races, circuit driving, or with increased engine output due to tuning.
Therefore, their shape may differ from the manufacturer's standard specified plugs, and plug life and low-speed performance may be slightly compromised.
However, on the other hand, they are developed and designed to fully demonstrate their performance even in extremely tuned engines and very harsh operating conditions, enduring such conditions with a wide range of heat ratings.
Please select the appropriate plug for your individual engine to achieve its full potential.
Points to note when choosing racing plugs:
Please check the screw size, plug type, and shape from the part number of your genuine plug or the plug you are currently using, and select the corresponding type.
Please refer to the manufacturer's website for guidance on how to choose the ignition end shape.
The heat rating needs to be selected considering the increase in combustion temperature due to improved engine output and operating conditions, in order to maintain the plug's ignition end at the optimal temperature range.
Simply increasing the heat rating alone will not improve engine performance.
Generally, heat ratings of 7-8 are used for street driving, 8-9 for track day specifications, and 9-10 for race specifications.
The presence or absence of a resistor in the plug makes almost no difference nowadays due to improvements in ignition system performance.
Resistor-type plugs will become the mainstream in the future.
Conversely, non-resistor type plugs may cause engine trouble in some models of some vehicle types.
In such cases, please be sure to use a resistor type.
