Racing Plug 94237

【NGK R0452A-10 Racing Plug 94237 ngk r0452a-10-94237】
Racing plugs, recommended for two-wheelers and four-wheelers, are available in various types aimed at further performance improvement when used in races, circuit driving, or with increased engine output due to tuning.
Therefore, their shape differs from the standard plugs specified by the manufacturer, and plug life and low-speed performance may be slightly compromised.
However, conversely, they are developed and designed to fully exhibit performance and withstand even in extremely tuned engines and very harsh operating conditions, with a wide range of heat ratings.
Please select the appropriate plug for your individual engine to achieve its full performance.
Precautions 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 igniter tip shape.
The heat rating needs to be selected to maintain the plug's igniter tip temperature within the optimal range, taking into account the increase in combustion temperature due to improved engine output and operating conditions.
Simply increasing the heat rating alone will not improve engine performance.
Typically, grades 7-8 are used for street driving, 8-9 for track day specifications, and 9-10 for race specifications.
Regarding the presence or absence of a resistor in the plug, there is almost no difference recently due to the improvement in ignition system performance.
Resistor types will become the mainstream in the future.
Conversely, non-resistor types may cause engine trouble in some models of some vehicle types.
In such cases, please be sure to use a resistor type.
