Racing Plug 7506

【NGK R0465B-10 Racing Plug 7506 ngk r0465b-10-7506】
Racing plugs recommended for two-wheeled and four-wheeled vehicles 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 specified plugs, and plug life and low-speed performance may be slightly compromised.
However, on the other hand, they are developed and designed to fully demonstrate their performance even in extremely tuned engines and under very severe operating conditions, and are set to withstand high heat ratings.
Please select the appropriate plug for your individual engine to fully unleash its performance.
Points to consider when choosing racing plugs
Determine the thread size, plug type, and shape from the part number of the genuine plug or the plug currently in use, and then select the corresponding type.
Please refer to the manufacturer's website for guidance on how to choose the igniter shape.
The heat range needs to be selected to maintain the igniter tip temperature within the optimal range, taking into account the increased combustion temperature due to improved engine output and operating conditions.
Simply increasing the heat range alone will not improve engine performance.
Generally, heat ranges 7-8 are used for street driving, 8-9 for track day specifications, and 9-10 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.
Resistor-type plugs will become the mainstream going forward.
Conversely, non-resistor type plugs may cause engine trouble in some models of certain vehicle types.
In such cases, always use a resistor-type plug.
