The aFe Silver Bullet throttle body spacer kit for 2007–2013 Chevrolet Silverado and GMC Sierra 1500 (V6 4.3L) lengthens the intake track and uses a serrated/helix entry design to create air turbulence just before the intake, increasing intake air speed and improving throttle response while reducing intake whistle. CNC-machined from 6061-T6 billet aluminum, the kit installs using factory mounting locations and includes a gasket for sealing.
