◎ Please note that, in some cases, the illustrations and photos may vary from the actual hardware.
This product is so designed to achieve a higher compression ratio than stock engines. As for the fuel, high-octane gasoline
should always be used. In case regular gasoline is used, abnormal combusiton takes place, and the engine cannot achieve its
original performance. Moreover, it is highly likely that the piston will break down, leading to serious breakdown. Before installing,
make sure that no regular gasoline remains in the fuel tank. In case regular gasoline is remaining in the fuel tank, do replace it
with high-octane gasoline.
Please be sure to replace the spark plug with CR8HSA (NGK) or U24 FSR-U (DENSO). In the case of a non-resistive plug,
please replace with C8HSA (NGK) or U24 FS-U (DENSO).Subsequently, choose and use a right spark plug with the right level,
depending on the degree of burning of the spark plug electrode section.
The installation of this product will increase the power of your vehicle. So use of a stock sprocket will result in hard wears of
parts, not only adversely affecting the engine life, but also breaking the engine in the worst case. Please replace the sprocket
with the high-geared one.
