Airaid 07-10 Ford F-150/Explorer 4.0L 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.Installation InstructionsThis Part Fits: Year Make Model Submodel 2007-2008 Ford Explorer Eddie Bauer 2007-2008 Ford Explorer Limited 2007-2008 Ford Explorer XLT 2008,2010 Ford F-150 FX2 2007-2010 Ford F-150 STX 2008 Ford F-150 THE 60TH ANNIVERSARY EDITION 2007-2010 Ford F-150 XL 2007-2010 Ford F-150 XLT
