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. 91-02 Jeep 2.5L 4 Cyl only Fitment: Jeep Wrangler Base 1991 Jeep Wrangler Base 1992 Jeep Wrangler Base 1993 Jeep Wrangler Islander 1991 Jeep Wrangler Rio Grande 1995 Jeep Wrangler S 1991 Jeep Wrangler S 1992 Jeep Wrangler S 1993 Jeep Wrangler S 1994 Jeep Wrangler Sahara 1991 Jeep Wrangler SE 1995 Jeep Wrangler SE 1997 Jeep Wrangler SE 1998 Jeep Wrangler SE 1999 Jeep Wrangler SE 2000 Jeep Wrangler SE 2001 Jeep Wrangler SE 2002
