A throttle body spacer is a ring installed between the intake manifold and the throttle body. The spacer lengthens the intake manifold, creating additional volume for the incoming air. The extra capacity improves driveability, increasing the overall enjoyment of the truck. If you have a 2014-2024 Silverado or Sierra 1500 with a 5.3-liter, the AIRAID PowerAid Throttle Body Spacer (Part No. S100290) available from AmericanTrucks is for you.
The 6061-T6 aluminum AIRAID Throttle Body Spacer enhances torque from off-idle to approximately 3,000 rpm. It utilizes a patented Helix Bore design to swirl the incoming air. The spinning increases the air velocity, helping to atomize the air/fuel passing the intake valve and entering the combustion chamber.
The installation of the AIRAID Throttle Body Spacer is straightforward. It requires a 10mm socket and ratchet, a 10mm wrench, and a flat-tip screwdriver and should take less than an hour.
Installing the spacer starts by removing the intake ducting. The ducting clamp(s) must be unthreaded, allowing the hose to be moved aside. Four 10 mm-headed bolts secure the throttle body to the intake manifold and must be detached. The throttle body releases from the manifold with the bolts removed.
The spacer is slipped into the manifold, resting against the factory gasket. An additional gasket is placed on the outer side of the spacer, and the throttle body is secured to the manifold with longer bolts supplied with the spacer. Thus, the throttle body spacer is sandwiched between the throttle body and the manifold. Lastly, the intake ducting is reattached to the throttle body.
The AIRAID PowerAid Throttle Body Spacer will release the engine’s performance and mileage potential without requiring major engine modifications. Bolt one on today.
Note:Ā Currently, the AIRAID PowerAid Throttle Body Spacer does not meet California or states adopting California emissions standards.
