Airaid 07-13 Avalanche/Sierra/Silverado 4.8/5.3/6.0L PowerAid TB Spacer

The POWERAID Throttle Body Spacer is designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm. The spacer utilizes it’s unique, patented Helix Bore design to spin the incoming air charge as it passes through the throttle body spacer. The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture as the air charge enters the combustion chamber. The end result is more part-throttle torque and improved mid-range power.
The AIRAID Throttle Body Spacer is designed to enhance mid-range torque using a patented Helix Bore which spins intake air going through the throttle body spacer. Includes mounting hardware.
