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.This Part Fits: Year Make Model Submodel 2015 Chevrolet Silverado 2500 HD High Country 2007-2015 Chevrolet Silverado 2500 HD LT 2007-2015 Chevrolet Silverado 2500 HD LTZ 2007-2015 Chevrolet Silverado 2500 HD WT 2007 Chevrolet Silverado 2500 HD Classic LS 2007 Chevrolet Silverado 2500 HD Classic LT 2007 Chevrolet Silverado 2500 HD Classic WT 2007 Chevrolet Silverado 3500 Classic LS 2007 Chevrolet Silverado 3500 Classic LT 2007 Chevrolet Silverado 3500 Classic WT 2015 Chevr
