Yeah, they're saving THEIR gas money - courtesy of all the morons that will be stupid enough to buy one of these things.
The supposed explanation of how this thing works had me ROTFLMAO - converts nitrogen in the air into "nitro gas" (maybe it's the "Fifth Element"?), which "helps combust unburned hydrocarbons in the air intake manifold".
Well, I sure as hell hope there aren't any "unburned hydrocarbons" (ie, gas or diesel) in my intake manifold - BECAUSE IT'S THE FRIGGIN AIR INTAKE MANIFOLD!!!!!
