AEM Filters Brute Force Air Induction System for 91-95 Jeep Wrangler YJ with 4.0L 6 Cylinder Engine

Dyno tested to deliver more torque and more horsepower. How does a 14.9-horsepower gain @ 5,400 RPM for your 4.0L engine sound? Torque gains of over 14.6 ft./lbs. were also achieved at 5,300 RPM. AEM performs three-axis testing to qualify gains made at different throttle positions and to ensure extra power at every point across the rpm band. AEM Cold Air Intake systems are individually tuned in length and diameter with the highest standards of construction. Kits include a powder coated CNC mandrel-bent 6061 aluminum air tube with TIG-welded fittings and brackets. AEM now includes DRYFLOW Synthetic filters with their Brute Force Induction Systems. Made from a polyester synthetic media that never degrades over time, meaning it delivers the same filtration efficiency after its 50th cleaning cycle as it does right out of the box. The powder-coated steel heat shield blocks warm engine bay air, allowing the colder (horsepower producing) air though the intake. Made in U.S.A.
