Airaid 91-06 4.0L Jeeps 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 1991-1993 Jeep Cherokee Base 1991-1992 Jeep Cherokee Briarwood 1996,1998-2001 Jeep Cherokee Classic 1993-1997 Jeep Cherokee Country 1991-1992 Jeep Cherokee Laredo 1991-1992,1998-2001 Jeep Cherokee Limited 1994-2001 Jeep Cherokee SE 1991-2001 Jeep Cherokee Sport 1999-2004 Jeep Grand Cherokee Laredo 1999-2004 Jeep Grand Cherokee Limited 2004 Jeep Grand Cherokee Special Edition 2002 Jeep Grand Cherokee Sport
