Q:how fuel effecient is this?
A:A throttle body spacer is a component added to the throttle body of a fuel injection engine to improve fuel efficiency and add power to the engine. The throttle body has a similar function to the carburetor on a non-fuel injection engine. A carburetor, however, controls the mix of air and fuel that is sent into the engine's cylinders, while a throttle body only regulates the air flow to the engine, in cooperation with the fuel injection system.
