When the voltage drops under high loads, such as sudden acceleration, the performance of those devices will decrease. Hot Inazuma uses its electrical storage capacity to release stored electricity when the supply voltage to each electrical component and ignition system drops, providing stable power to each electrical component. As a result, the potential performance that the car originally possesses is brought out. By installing Hot Inazuma... There are many benefits, such as increased torque, improved response, stable headlight illumination, reduced audio noise, extended battery life, and improved fuel efficiency. Especially the "Hyper" version covers the entire RPM range from city driving to sports driving, while improving the charging and discharging speed at low RPM, further enhancing the effect. It seems that it was used, so it has some scratches and dirt. If you don't mind.
