Founded in 1997, AIRAID advanced the automotive aftermarket industry with the introduction of its AIRAID Intakes brand of air intake systems. Initially developed for light trucks and sport utility vehicles, the first AIRAID kits combined an open-element cotton gauze filter with an intake tube to produce an innovative, easy-to-install intake kit which dramatically increased air flow, horsepower and torque while improving overall engine performance. Within five years, explosive sales proved that Airaid's blend of technology and state-of-the-art materials were just what the performance parts market was missing. AIRAID Premium Filters were introduced in November 2002, securing Airaid's place as a leader in air management for both gasoline and diesel power plants. Airaid's product base now includes a wide variety of AIRAID Intake Systems, PowerAid Throttle Body Spacers and OEM replacement filters. Each AIRAID product line is the result of exhaustive research and development. Our in-house engineering team consists of both mechanical and industrial design engineers using the latest 3-D CAD modeling equipment to produce advanced designs that make more power right out of the box. A portable 3-D scanner and rapid prototyping machine allows AIRAID to test new products on our in-house Superflow flow bench and verify the unmatched fit, finish, and style that AIRAID customers demand. All products are then tested on our all-wheel-drive Mustang chassis dynamometer to produce real-world performance numbers. All AIRAID Premium Filters are produced in-house using only the finest materials available and highly specialized manufacturing equipment to ensure a level of quality control no other filter company can match. This is just one of many reasons why all of Airaid's filters are backed by our No Hassle Lifetime Warranty. All of Airaid's product lines are proudly manufactured in the USA. The POWERAID Throttle Body Spacer is designed to enhance mid-range torque using a patented Helix Bore which spins intake air going through the throttle body spacer. Includes all mounting hardware. 91-06 4.0L Jeeps Fitment: Jeep Cherokee Base 1991 Jeep Cherokee Base 1992 Jeep Cherokee Base 1993 Jeep Cherokee Briarwood 1991 Jeep Cherokee Briarwood 1992 Jeep Cherokee Classic 1996 Jeep Cherokee Classic 1998 Jeep Cherokee Classic 1999 Jeep Cherokee Classic 2000 Jeep Cherokee Classic 2001 Jeep Cherokee Country 1993 Jeep Cherokee Country 1994 Jeep Cherokee Country 1995 Jeep Cherokee Country 1996 Jeep Cherokee Country 1997 Jeep Cherokee Laredo 1991 Jeep Cherokee Laredo 1992 Jeep Cherokee Limited 1991 Jeep Cherokee Limited 1992 Jeep Cherokee Limited 1998 Jeep Cherokee Limited 1999 Jeep Cherokee Limited 2000 Jeep Cherokee Limited 2001 Jeep Cherokee SE 1994 Jeep Cherokee SE 1995 Jeep Cherokee SE 1996 Jeep Cherokee SE 1997 Jeep Cherokee SE 1998 Jeep Cherokee SE 1999 Jeep Cherokee SE 2000 Jeep Cherokee SE 2001 Jeep Cherokee Sport 1991 Jeep Cherokee Sport 1992 Jeep Cherokee Sport 1993 Jeep Cherokee Sport 1994 Jeep Cherokee Sport 1995 Jeep Cherokee Sport 1996 Jeep Cherokee Sport 1997 Jeep Cherokee Sport 1998 Jeep Cherokee Sport 1999 Jeep Cherokee Sport 2000 Jeep Cherokee Sport 2001 Jeep Grand Cherokee Laredo 1999 Jeep Grand Cherokee Laredo 2000 Jeep Grand Cherokee Laredo 2001 Jeep Grand Cherokee Laredo 2002 Jeep Grand Cherokee Laredo 2003 Jeep Grand Cherokee Laredo 2004 Jeep Grand Cherokee Limited 1999 Jeep Grand Cherokee Limited 2000 Jeep Grand Cherokee Limited 2001 Jeep Grand Cherokee Limited 2002 Jeep Grand Cherokee Limited 2003 Jeep Grand Cherokee Limited 2004 Jeep Grand Cherokee Special Edition 2004 Jeep Grand Cherokee Sport 2002 Jeep Wrangler 65th Anniversary Edition 2006 Jeep Wrangler Base 1991 Jeep Wrangler Base 1992 Jeep Wrangler Base 1993 Jeep Wrangler Islander 1991 Jeep Wrangler Islander 1992 Jeep Wrangler Renegade 1991 Jeep Wrangler Renegade 1992 Jeep Wrangler Renegade 1993 Jeep Wrangler Renegade 1994 Jeep Wrangler Rubicon 2003 Jeep Wrangler Rubicon 2004 Jeep Wrangler Rubicon 2005 Jeep Wrangler Rubicon 2006 Jeep Wrangler Sahara 1991 Jeep Wrangler Sahara 1992 Jeep Wrangler Sahara 1993 Jeep Wrangler Sahara 1994 Jeep Wrangler Sahara 1995 Jeep Wrangler Sahara 1997 Jeep Wrangler Sahara 1998 Jeep Wrangler Sahara 1999 Jeep Wrangler Sahara 2000 Jeep Wrangler Sahara 2001 Jeep Wrangler Sahara 2002 Jeep Wrangler Sahara 2003 Jeep Wrangler Sahara 2004 Jeep Wrangler SE 1994 Jeep Wrangler SE 1995 Jeep Wrangler SE 2005 Jeep Wrangler SE 2006 Jeep Wrangler Sport 1997 Jeep Wrangler Sport 1998 Jeep Wrangler Sport 1999 Jeep Wrangler Sport 2000 Jeep Wrangler Sport 2001 Jeep Wrangler Sport 2002 Jeep Wrangler Sport 2003 Jeep Wrangler Sport 2004 Jeep Wrangler Sport 2005 Jeep Wrangler Sport 2006 Jeep Wrangler Unlimited 2004 Jeep Wrangler Unlimited 2005 Jeep Wrangler Unlimited 2006 Jeep Wrangler Unlimited Rubicon 2005 Jeep Wrangler Unlimited Rubicon 2006 Jeep Wrangler X 2002 Jeep Wrangler X 2003 Jeep Wrangler X 2004 Jeep Wrangler X 2005 Jeep Wrangler X 2006
