I recently saw an ad for the SpiralMax Turbo Air Twister. Its low price, around $90, made me question how well it works. It consists of metal pieces that are placed in the air intake hose which are supposed to lengthen the passageway for air towards the engine, giving better vaporization, more HP, torque etc...do you think it is a good investment? Do you know anyone who has one?
