Racing Plugs 92278

【NGK R0451C-10 Racing Plug 92278 ngk r0451c-10-92278】
Racing plugs, recommended for two-wheelers and four-wheelers, are available in various types to further improve performance when used in races, circuit driving, or with increased engine output due to tuning.
Therefore, their shape differs from the manufacturer's standard plugs, and plug life and low-speed performance may be slightly compromised.
However, conversely, they are developed and designed to fully demonstrate their performance and withstand even extremely tuned engines and very severe operating conditions, and are available in a wide range of heat ratings.
Please select the appropriate plug for your individual engine to achieve full performance.
Important points when choosing racing plugs
Please find the screw size, plug type, and shape from the part number of your genuine plug or the plug you are currently using, and then select the corresponding type.
Please refer to the manufacturer's website for guidance on how to choose the ignition tip shape.
The heat rating needs to be selected considering the increase in combustion temperature due to increased engine output and operating conditions, in order to maintain the plug's ignition tip temperature within the optimal range.
Simply increasing the heat rating alone will not improve engine performance.
Generally, heat ratings of 7 to 8 are used for street driving, 8 to 9 for track day specifications, and 9 to 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.
In the future, resistor types will become the mainstream.
Conversely, non-resistor types may cause engine trouble in some models of some vehicle types.
In such cases, always use a resistor type.
