The PowerAid Throttle Body Spacer bolts in front of the throttle body and causes a ‘vortex’ effect to the air intake charge. This causes the air/fuel mixture to atomize more completely, which creates a more efficient combustion. Adds up to 5 horsepower & 21 ft/lbs of torque, and can increase gas mileage by up to 4 MPG. 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.
