i thinking about buying the Rusty's offroad throttle body spacer its an one inch spacer claims 10 hp at the wheels and 1 to 2 mpg improvement is it worth the 60 dollars??

	Throttle body spacer A throttle body spacer is designed to improve the quality of the airflow, allowing air that is more condensed and, thus, more oxygen laden, to enter the combustion chamber. The result of this is a more efficient burn, which serves to release more energy from the fuel, making more horsepower available.
