I'm interested in getting one of those throttle body spacers that creates that "Vortex" of wind. The ad states "The unique dyno-proven "Helix Bore" causes a spinning action of the incoming air charge as it passes through the throttle body. This beneficial air-charge carries into the combustion chamber, producing a super-atomized mixture and resulting in tremendous gains in mid-range power, torque and fuel efficiency."
Is it worth $64? Have any of you ever tried it? Ant feed back would be helpful.
