Airaid 99-06 Chevy/GMC Silverado/Sierra/SUV 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 2002-2006 Cadillac Escalade Base 2003-2006 Cadillac Escalade ESV Base 2002-2006 Cadillac Escalade EXT Base 2002-2005 Chevrolet Avalanche 1500 Base 2005-2006 Chevrolet Avalanche 1500 LS 2005-2006 Chevrolet Avalanche 1500 LT 2002-2003 Chevrolet Avalanche 1500 North Face 2002-2003 Chevrolet Avalanche 1500 On Road Edition 2003 Chevrolet Avalanche 1500 WBH 2004-2006 Chevrolet Avalanche 1500 Z66 2002-2006 Chevrolet Avalanche 1500 Z71 2
