usually advice ko use platinum spark plug for cefiro ... ordinary spark plug won't do ... just buy ngk planitum or bosch platinum any would do ....

22401-20J05 ... can't be used for cefiro ... cefiro has its own original spark plug ... kasi mas malakas yung makina kaya iba yung specs nito ...

NGK and bosch platinum is around 140 per piece ..... yung original is about 200+
