92-03 Dodge RAM, Dakota, Durango 5.2L, 5.9L Econoaid Throttle Body Spacer is designed to fit between your factory throttle body and your intake manifold. Econoaid Throttle Body Spacer spins the incoming air as it passes through the throttle body and over the Econoaid blades. The turbulent air charge is carried through past intake valves for better atomization and more complete combustion. The Econoaid Throttle Body Spacer will give you a crisper throttle response, along with better gas mileage. Unlike other spacers, the Econoaid Throttle Body Spacer installs easier and faster. The Econoaid is only a fraction of an inch thick, 0.030 inch actually. Other spacers are as much as a 1 inch thick, necessitating additional hardware, complicating installation and adding to cost. The main benefit of the Econoaid is the fuel savings. The results of this fuel saving device will always vary depending on vehicle type, driving habits, age of the vehicle, and driving environment, among other factors. However, from customer reports, the average vehicle will see an extra 1-3 miles per gallon and produce an extra 6-10 feet pounds of torque, which can be felt from the increased low-end throttle response. The Econoaid Throttle Body Spacer will pay for itself in no time, especially with current increasing gas prices. Econoaid come complete with all necessary gaskets, detailed installation instructions, and reuses the factory hardware. Installation requires only simple hand tools and usually only takes about 30 minutes. Econoaid made in the USA.
