Racing Plugs 5962

[NGK R6061-10 Racing Spark Plug 5962 ngk r6061-10-5962]
Racing spark plugs, recommended for two and four-wheeled vehicles, come in various types designed to further enhance performance when used in races, circuit driving, or with engines whose output has been increased through tuning.
Consequently, their shape differs from the manufacturer's standard plugs, and there may be a slight compromise in plug lifespan and low-speed performance.
However, conversely, they are developed and designed to fully demonstrate their performance even in extremely tuned engines and under 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 its full performance.
Important points when choosing racing spark plugs:
From the part number of your genuine plug, or the plug currently in use, determine 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 ignition 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 maintain the ignition end temperature of the plug within the optimal temperature range.
Simply increasing the heat rating alone will not improve engine performance.
Typically, for street use, numbers 7 to 8 are used; for track day specifications, 8 to 9; and for race specifications, 9 to 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 the mainstream in the future.
Conversely, non-resistor types may cause engine trouble in some models of some vehicle types.
In such cases, always use a resistor type.
