Airaid 01-07 Silverado / Sierra Classic 4.3L V6 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 2001-2005 Chevrolet Silverado 1500 Base 2001-2006 Chevrolet Silverado 1500 LS 2001-2005 Chevrolet Silverado 1500 LT 2002-2006 Chevrolet Silverado 1500 WT 2004 Chevrolet Silverado 1500 Z71 2002-2005 GMC Sierra 1500 Base 2002 GMC Sierra 1500 HT 2001-2003,2006 GMC Sierra 1500 SL 2001-2004 GMC Sierra 1500 SLE 2001-2004 GMC Sierra 1500 SLT 2002-2006 GMC Sierra 1500 WT
