      Improves Horsepower with Minimal Effort. Installing the Airaid PowerAid Throttle Body Spacer will improve your system's vacuum response. This will allow your vehicle to generate better airflow and more horsepower without having your engine work harder.

      Increases Airflow and Acceleration Gains. The Airaid PowerAid Throttle Body Spacer regulates the airflow that goes into your engine. By permitting more air to go into the engine, you gain more acceleration and torque while on the road, enhancing mid-range power.

      Boasts the Patented Helix Bore Design. The Helix Bore design spins the incoming air change as it passes through the body spacer. This motion boosts the velocity of the incoming air, which contributes to better atomization of the air/fuel mixture as the air charge enters the combustion chamber.

      Installs Quickly. The Airaid Power Air Throttle Body Spacer kit comes with all the parts you need to assemble the piece. Each component is made from aircraft quality aluminum, which smoothens and eases the installation process. It will take you less than an hour to install the throttle body spacer.

      Application. The Airaid PowerAid Throttle Body Spacer is designed to fit 2014-2018 5.3L GMC Sierras.

      Please Note. This Throttle Body Spacer is not legal for use in California or any other states adopting California emission standards.

        Quick install

        The science behind it is more hp, etc. Did it with a cold air intake so dont know if its making a difference. To install it, it's a job someone could get their kids involved with it's so easy. Four bolts and your done.

        Easy to install

        Easy to install , did along with cold air intake. Both together took about 45 minutes while watching the their videos online . Improved throttle response. Haven’t had long enough to assess gas mileage improvement . Overall would buy again .
