These times when gas prices are always fluctuating, you would surely want to gain more power for your ride by doing simple customizations without sacrificing much fuel. One possible way is to add a throttle body spacer in your air intake system. This component increases the amount of air flowing into the central plenum of the intake manifold, thus improving the mix of air and fuel processed in the engine. Whether you have a fuel-injected or a carbureted engine, installing this add-on could actually be beneficial in some ways. However, before proceeding with the upgrade, see first if one from Airaid's PowerAid line is worth your time and money.

We tested this component on a Toyota Hilux with a V6 and a Honda GX240 with a carburetor, and here is what we have to say:
- Installing the component was very easy--what with all the installation hardware provided. It just needed to be bolted at the back of the throttle body just before the intake manifold. The entire procedure took only fifteen minutes for the Hilux and the GX240.
- The component was made from a very solid aluminum material. It was an inch thick, and when we pounded it against the ground, it made a deep sound that indicated no hollow part inside.
- The helix design borne into the throttle body spacer was well-engineered. The helix grooves were equal in depth and there were no bumps anywhere.
- The component was indeed compatible with both diesel and gas. That was a great plus because we were able to use any vehicle for the test.
- The thirty-minute drive with the GX240 was fruitful. The engine responded better, and we experienced a 4-point increase in horsepower and a 25-point increase in torque output.
- During the thirty-minute drive we had with the Hilux, we barely noticed any increase in horsepower and torque. Also, there was no considerable improvement in gas mileage.
Even though power gain from the use of a throttle body spacer is questionable, we still had quite a number of good points to stress out from our test. This kind of add-on seemed to complement carbureted engines better. When it comes to its appearance and construction, it looked dependable enough. Still, your experience will determine if this product is really a good one.
