Racing Plugs 7179

【NGK R6690-11 Racing Plug 7179 ngk r6690-11-7179】
Racing plugs recommended for two-wheel and four-wheel vehicles 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, on the other hand, they are developed and designed to fully demonstrate performance even in extremely tuned engines and very severe operating conditions, and can withstand such conditions, with a wide range of heat ratings up to high values.
Please select the appropriate type for each engine to unleash its full performance.
Points to consider when choosing racing plugs
Refer to the part number of your genuine plug or the plug you are currently using to 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 range needs to be selected to maintain the plug's ignition end temperature within the optimal range, taking into account the rise in combustion temperature due to increased engine output and operating conditions.
Simply increasing the heat range will not improve engine performance.
Generally, heat ranges of 7-8 are used for city 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 improved ignition system performance.
In the future, resistor types will become mainstream.
Conversely, non-resistor types may cause engine trouble in some models of certain vehicles.
In such cases, always use resistor type plugs.
