{"product_id":"ngk-r6254e-9-5583","title":"Racing Plug 5583","description":"【NGK R6254E-9 Racing Plug 5583 ngk r6254e-9-5583】\u003cbr\u003e\n 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 engines whose output has been increased through tuning.\u003cbr\u003e\n Therefore, their shape may differ from the manufacturer's standard plug, and plug life and low-speed performance may be slightly sacrificed.\u003cbr\u003e\n However, on the other hand, they are developed and designed to fully demonstrate performance even in highly tuned engines and under very severe operating conditions, and are set with a wide range of heat ratings.\u003cbr\u003e\n Please select the appropriate plug for your engine to achieve full performance.\u003cbr\u003e\n Important points when choosing a racing plug\u003cbr\u003e\n Please check the screw size, plug type, and shape from the part number of your genuine plug or the plug you are currently using, and select the corresponding type.\u003cbr\u003e\n Please refer to the manufacturer's website for guidance on how to choose the igniter tip shape.\u003cbr\u003e\n The heat rating needs to be selected to maintain the igniter tip temperature within the optimal range, taking into account the increase in combustion temperature due to increased engine output and operating conditions.\u003cbr\u003e\n Simply increasing the heat rating alone will not improve engine performance.\u003cbr\u003e\n For mainly street use, numbers 7-8 are used; for track day specifications, numbers 8-9; and for racing specifications, numbers 9-10.\u003cbr\u003e\n The presence or absence of a resistor in the plug makes almost no difference nowadays due to improvements in ignition system performance.\u003cbr\u003e\n Resistor-type plugs will become the mainstream in the future.\u003cbr\u003e\n Conversely, non-resistor types may cause engine trouble in some models of some vehicle types.\u003cbr\u003e\n In such cases, please be sure to use a resistor-type plug.\u003cbr\u003e\n *The image is for illustrative purposes only, and the design and specifications of the products shown are subject to change without prior notice.
