AirAid Chevy Silverado PowerAid Throttle Body Spacer 01-04 6.6L Duramax Diesel

These AirAid PowerAid Throttle Body Spacers are designed to greatly improve the low-end torque and horsepower characteristics of your engine. PowerAid accomplishes this by spacing the throttle body by 1" and adding a dyno-proven, helix-style bore. As the intake air passes through the spacer, the helix bore creates a vortex action that increases atomization, creating a more complete combustion and efficiently burning engine. The results are improved driveability and increased fuel efficiency. The AirAid PowerAid spacer is legal in all 50 USA states, will not void your new car warranty, and can be used with any grade of fuel.
