Is that a hydrogen generator...oh, boy, better do some research and slowly walk away from the hype machine! There has been a ton of conjecture on adding hydrogen gas to your intake stream across many platforms/makes/models. Pretty much anyone who doesn't have a vested interest in selling you something has come to the same conclusion that none are worth the time/effort/$$. YMMV.
