Can you do away with spacer on a ford 351m intake?

Will a throttle body spacer make a difference to your expedition 1997 and how would I install it?

= Ford Throttle Body Spacer Description = In order for the engine of a Ford to run well, it needs a high volume of dense air coming into the combustion chamber at all times. Increasing the amount of air coming in to the engine will give the engine a power boost, and the Ford throttle body spacer is just the part to do the job. When installed, it will sit between the throttle body and the cold air intake. As the air comes into the Ford throttle body spacer, it is accelerated by a set of ridges that induces a vortex pattern into the flow. This allows the cold sir intake to move air in quicker. The Ford throttle body spacer also compresses the air, so that a larger amount will fit into the combustion chamber. The engine's computer will then increase the amount of fuel injected into the mixture, and when the combination is ignited, the resulting explosion will push the pistons down with more force. With the Ford throttle body spacer installed, the vehicle will gain several horsepower, and it will also see an increase in gas mileage. Because the hardware and gaskets that are required to install the Ford throttle body spacer are included in the kit, all that will be needed is a few simple tools. After the cold air intake is disconnected from the throttle body, and the gasket removed, the Ford throttle body spacer and gaskets can be installed. We carry the Ford throttle body spacer for many models in our online catalog, and with an easy, toll-free phone call or through our secure web site, the unit can be easily ordered. http://www.car-stuff.com/fordthrottlebodyspacer.htm
