It has help me ignition system boost which increases the original 12V to 15.8V. It has also increase the horsepower as the ignition system strengthening provides better electricty power. Thus, it gives me a totally brand new feeling! Moreover, it helps with with the decrease fuel wasting more effectively. As I can feel that the burning effeciency becomes better and better after the ignition performance is promoted. It helps to use every drop of gasoline effectively by decrease fuel wasting up to 20%! What are you waiting for? I have no regret buying it and I believe you will not regret as well!
