okok.. : ) actually i dun quite know the product, but just share what i got k...
Previously it was designed like ball shaped, it helps in rearranging molecule, some ppl stick it near fuel tank and claim got better fuel efficiency, most ppl put it near either ecu or air intake...
Now the newer version came out, it's a stick shaped and put inside place where we used to light up cigarette?? dunno the scientific name lah~~ haha... It claims will help regulate molecule even better and thus improve car performance.. : )
According to my honest mech, green colour you can feel the difference in 2 hrs, blue in 12 hrs, black in one day, higher price greater effect, he also offer me to try but i rejected... : ) Reason why i wanna ask this is because my car is old and most of the wiring and electronic object are oxydating, used to install a voltage stabilizer but the effect wasn't too good and now pricing and brainding also all mess up so not intend to buy any... then saw lots of ferrari, lambo (in advertisement) put this in their car so just try to get feeedbacks from you guys LOL~~
