      Economical Performance Upgrade. The aFe Silver Bullet Throttle Body Spacer is an effective and economical solution to level up your Sierra’s performance. This Throttle Body spacer is engineered to create turbulence right at the junction where the throttle body and intake manifold meet. This extra turbulence improves the air & fuel mix, resulting in better combustion. This increases horsepower and torque, and improves throttle response, especially in low revs.

      Precision-Machined Billet Aluminum Construction. The aFe Silver Bullet Throttle Body Spacer is constructed from 6061-T6 billet aluminum which means it is both lightweight and strong. The unit is precision-machined for a tight fit. Additionally, this throttle body spacer features a serrated, helix combo design that works to reduce that irritating intake whistling found in throttle body spacers featuring a helix-only design.

      Simple Bolt-On Installation. All the installation hardware needed is included with the aFe Silver Bullet Throttle Body Spacer for a simple installation. The throttle body spacer bolts on directly between the throttle body and intake manifold, without modifications.

      Backed by a 2-Year Limited Warranty. The aFe Silver Bullet Throttle Body Spacer is backed by a 2-year limited warranty covering factory defects. Please visit the manufacturing website for more details.

      Application. The aFe Silver Bullet Throttle Body Spacer fits 2014-2023 5.3L GMC Sierra 1500 models.
