Racing plug 2946

【NGK R0045G-10 Racing Plug 2946 ngk r0045g-10-2946】
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 engines tuned for higher output.
Therefore, their shape differs from the manufacturer's standard plugs, and plug life and low-speed performance may be slightly compromised.
On the other hand, they are developed and designed to fully demonstrate performance and withstand even extremely tuned engines and very severe operating conditions, with 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
From the part number of your genuine plug or the plug you are currently using, determine the thread size, plug type, and shape, and then select the corresponding type.
Please refer to the manufacturer's website for how to choose the firing end shape.
The heat rating needs to be selected considering the increase in combustion temperature due to engine output improvement and operating conditions, in order to keep the plug's firing end temperature within the optimal 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.
Regarding the presence or absence of a plug resistor, there is almost no difference recently 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.
