The AIRAID PowerAid throttle body spacer for 2001–2007 Silverado and Sierra Classic 4.3L V6 applications uses a patented Helix Bore to spin the intake air through the spacer, increasing velocity and improving atomization of the air/fuel mixture to enhance part-throttle torque and mid-range power. The spacer is a bolt-on upgrade with included mounting hardware and installs using common hand tools.
