Is the air raid throttle body spacer just a joke or what? I've heard that these don't really do anything and that it is all a scam. Has anybody here got one and have things to say about it, i could care less about the extra power, I would however like to improve efficiency in the combustion chamber.

 

Vehicular snake oil in my opinion......Unless you buy the fuel saver magnets and 12v super charger to go with it.
