AEM Cold Air induction systems create MORE horsepower than ANY intake system on the market. Only AEM induction systems feature CNC mandrel-bent 6061 aluminum intake pipes that are individually tuned in both length and diameter to maximize power in each application. Every AEM intake is powder coated and has TIG-welded fittings and brackets. For filtration, AEM utilizes its new lightweight urethane, four-layer cotton-gauze filter that features a redesigned air horn that makes an additional 1-3 HP on our Air Induction Systems. All AEM air induction systems are C.A.R.B exempt and come with complete installation hardware, comprehensive instructions, AEM decal and license plate frame.
