A few months back, I came across this website that guide that teaches one person how to build a kit that helps to save on gas & fuel for the vehicle.
And from the reviews in the internet, this is real. And there are lots of people that has save lots of $$.
I did not think it is attractive at that time, as we as Malaysians were still enjoying pretty low fuel price.
The best is, you don't pay thousands to modify your car. All you need is just a kit and you are good to go.
I will share with you more concepts & benefits, but you can find those info per below:
