Our PowerAid xb scion  Throttle Body Spacers are manufactured from the highest quality Aircraft Grade Billet 6061-T6 Aluminum. Each PowerAid is specifically designed for your application. Our kits always include the necessary gaskets, hardware, and precision brackets to maintain proper geometry with the factory components. The PowerAid Spacer xb can be installed in less than an hour using common hand tools with no drilling or cutting required scion .

• Well, we have one throttle body spacer installed and dyno'dour results are simple, the best we achieved with bolt ons, with the Scion, was 101 HP to the wheels.
• After the installation of the OBX throttle body spacer, the dyno jumped to 103.61 HP to the wheels.
• This results in a 2.61 true increase, to the wheels, for the Scion throttle body spacer on our '06.

Given that most owners scion will spend more scion money on less power producing parts, it is still hard to scion understand why some can't seem to escape the results in their own mind and install this throttle body spacer proven power producer,scion for far less money than these other mods. We also painted our OBX throttle scion  body spacer to match our engine theme; this was simply done by using some self etching primer and an aluminum scion friendly paint color of your choice.In a  fuel injection engine the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver input. scion The throttle body is usually located between the air filter box and the intake manifold scion and usually attached to, or near, the mass airflow sensor scion.

The largest piece inside the throttle body is the throttle plate, which is a butterfly valve that regulates the airflow scion.

On many cars, the accelerator pedal motion is communicated scion through the throttle cable, which activates the throttle linkages, which moves the throttle plate. In cars with electronic throttle control (also known as "drive-by-wire"), an electric motor controls the throttle linkagesscion and the accelerator cable connects scion not to the throttle body but to a sensor. The Engine Control Unit (ECU) determines the throttle opening. On some modern cars, the accelerator cable is replaced by a pedal position sensor, which sends the pedal position to the ECU.

Most carburetor (as opposed to fuel-injected)engines have a single carburetor, though some engines use multiple carburetors. Older engines used updraft carburetors, where the air enters from below the carburetor and exits through the top. This had the advantage of never "flooding" the engine, as any liquid fuel droplets would fall out of the carburetor instead of into the intake manifold; it also lent itself to use of an oil bath air cleaner,where a pool of oil below a mesh element below the carburetor is sucked up into the mesh and the air is drawn through the oil covered mesh; this was an effective system in a time when paper air filters did not exist scion.
