      Enhanced Performance and Fuel Economy. The Airaid PowerAid Throttle Body Spacer is a simple and elegant solution for your Sierra’s power needs. It features a patented and precision-machined Helix Bore design that adds a spinning effect to the air charge. This results in better atomization of the fuel and air mixture while maintaining a constant velocity to the air charge up to the combustion chamber.

      High-Quality Construction. The PowerAid Throttle Body Spacer is made from high-grade 6061-T6 billet aluminum for outstanding strength, toughness, and durability. The precision-machining ensures superb performance and an excellent fit that maintains the proper geometry with the factory components.

      All Bolt-On Installation. The PowerAid Throttle Body Spacer features an application-specific design for a simple installation. No drilling is required and installation can be completed with the use of common garage tools.

      No Custom Tune or Reprogramming Required. Airaid’s engineers ensured that the PowerAid Throttle Body Spacer works perfectly with no other modifications required. It works using the Sierra’s factory tune so no additional tuning or reprogramming is required.

      Not CARB Certified. This PowerAid Throttle Body Spacer is EPA compliant but is not CARB certified at this time. It is not legal for use in California or any states that have adopted California emissions standards.

      Backed by 1-Year Limited Warranty. The PowerAid Throttle Body Spacer is warranted against defects in materials or workmanship. The warranty is valid only for the original purchaser and other exclusions will apply.

      Application. This Airaid PowerAid Throttle Body Spacer is designed to fit 2015 to 2018 6.2L GMC Sierra 1500 models.
