Racing Plugs 6267

【NGK R7233-10 Racing Plug 6267 ngk r7233-10-6267】
Racing plugs recommended for two-wheelers and four-wheelers 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 differs from the manufacturer's standard plugs, and the plug's lifespan and low-speed performance may be slightly compromised.
However, on the other hand, they are developed and designed to fully perform and withstand even in extremely tuned engines or very severe operating conditions, with a wide range of heat ratings up to very high values.
Please select the appropriate plug for your individual engine to achieve full performance.
Points to note when choosing racing plugs
From the part number of your genuine plug or the plug you are currently using, check the thread size, plug type, and shape, then select the corresponding type.
Please refer to the manufacturer's website for guidance on how to choose the firing end shape.
The heat rating needs to be selected by considering the increase in combustion temperature due to improved engine output and operating conditions, in order to maintain the plug's firing end temperature within the optimal range.
Simply increasing the heat rating alone will not improve engine performance.
Primarily, for street use, ratings 7-8 are used; for track days, 8-9; and for racing, 9-10.
Regarding the presence or absence of a resistor in the plug, there is almost no difference recently due to improvements in ignition system performance.
Resistor types will become mainstream in the future.
Conversely, non-resistor types may cause engine trouble in some models of some vehicles.
In such cases, please be sure to use a resistor type.
