Airaid 97-03 Ford F-150 / 97-04 Expedition 5.4L 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.Installation InstructionsInstallation InstructionsThis Part Fits: Year Make Model Submodel 1997-2004 Ford Expedition Eddie Bauer 2004 Ford Expedition NBX 2004 Ford Expedition XLS 1997-2004 Ford Expedition XLT 2004 Ford Expedition XLT Sport 1997-2000 Ford F-150 Base 2000-2001 Ford F-150 Harley-Davidson Edition 2001-2003 Ford F-150 King Ranch 1997-2003 Ford F-150 Lariat 1997-2003 Ford F-150 XL 1997-2003 Ford F-150 XLT 2004 Ford F-150 Heritage XL 2004 Ford F-150 Heritage
