EVE200-552-1 / 200-552-P - Application Notes Bolt On Horsepower! PowerAid® with PowerPorts™. These units were specifically designed with the sport compact enthusiast in mind. These PowerAid® TBS's are equipped with our all-new PowerPorts™ option. The PowerPorts™ are specially located ports that allow for the use of owner provided power enhancements(such as Nitrous Oxide) or instrumentation sensors. PowerAid® Throttle Body Spacers were developed to enhance midrange power, torque, and fuel efficiency. The unique patented and dyno-proven "Helix Bore" of the PowerAid® TBS creates a spinning action of the incoming air-charge as it passes through the throttle body. This extremely beneficial aircharge carries all the way into the combustion chamber, producing a super-atomized flow, which produces tremendous gains in mid-range power and overall efficiency. All PowerAid® PowerPorts™ TBS's come complete with all mounting hardware, port block-off plugs, and easy to follow instructions.
