    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 .

            Good power and fuel saving

            I purchased this and cold air intake for my truck. I went to install both at the same time, but the spacer was missing the four bolts and washers. They sent me the missing parts and I received them quickly. It might have been a good thing, because I got to see what each item did for my truck. The cold air intake gave me lots of power, quick response, but it dropped my mpg down about 3 miles per gallon. I installed the spacer and I felt a little more power and my mpg went up 2.4 miles per gallon. I'm happy with both and would recommend this spacer.

            Throttle body

            I recieved my part very quickly and it arrived damaged. Call American Trucks and they had a new one shipped right away. Love the sound it makes when you press on the gas. Seems to also make a big difference in the lag I used to have in the gas paddle. It has a quicker response. Would definately recommend everyone to add this part.

            Waste of money

            These do nothing on a direct injection engine The vortex they claim to help with the air fuel mixture does not apply on a direct injection engine where the fuel injectors are directly in the cylinders. We tested on a 2015 Silverado and made no gains over 5 pulls on dyno. Tested same spacer but for bigger stingray engine and it lost 3hp over 5 pulls. These spacers do work on the older 5.3 engines but not on the newer ones. The power people claim is a placebo effect. You read gain power and you install and you "think i feel it" Just my 02
