I know of one, it costs around $6k FOB if your interested.

Imo, most magic fuel saving devices are just placebo effect devices.
Just because you installed something you unconciously change your driving habits slightly, just enough to produce the improvement in fuel economy your looking for.

I've tried a few of those gadgets some time in the past out of curiousity at a time when I didn't know any better.

Now that I know better, I don't.

Not an expert, just common sense combined with knowledge of how some things work....
Sir, san po ung testing center?

thanks & more POWER!
