Air Raid Throttle Body Spacer #450-613, the cost new is $104.00 The Poweraid TBS concept was developed to enhance midrange power, torque, and fuel efficiency. The unique dyno-proven "Helix Bore" of the Poweraid throttle body spacers 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 creates tremendous gains in midrange power and overall efficiency. This is the key element to the horsepower success. Fits all 2005 thru 2010 Mustang V6 4.0L/245 CI
