Racing Plug 4896

【NGK R7435-9 Racing Spark Plug 4896 ngk r7435-9-4896】
Racing spark plugs recommended for 2-wheel and 4-wheel vehicles come in various types, designed to further enhance performance when used with increased engine output due to racing, circuit driving, or tuning.
Therefore, their shape differs from the manufacturer's standard spark plugs, and plug life and low-speed performance may be slightly compromised.
However, on the other hand, they are developed and designed to perform fully and withstand extremely tuned engines and very harsh operating conditions, with a wide range of heat ratings.
Please select the appropriate plug for your individual engine to achieve its full performance.
Precautions when choosing racing spark 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 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 increased engine output and operating conditions, in order to maintain the plug's firing end temperature within the optimal range.
Simply increasing the heat rating will not improve engine performance.
Generally, heat ratings of 7-8 are used for city driving, 8-9 for track day specifications, and 9-10 for race specifications.
The presence or absence of a resistor in the spark plug makes almost no difference these days due to improvements in ignition system performance.
Resistor types will become the mainstream in the future.
Conversely, non-resistor types may cause engine problems in some models of certain vehicle types.
In such cases, please be sure to use a resistor type.
