The POWERAID® TBS concept was developed to enhance mid-range power, torque and fuel efficiency. The unique dyno-proven "Helix Bore" of the POWERAID® TBS causes a spinning action of the incoming air-charge as it passes through the throttle body. This extremely beneficial air-charge carries all the way into the combustion chamber, producing a super-atomized mixture, which produces tremendous gains in mid-range power and overall efficiency. This is the key element to the horsepower success behind each POWERAID® TBS.
