AEM Cold Air Intake 21-471

AEM Cold Air induction systems create MORE horsepower than cheaper inferior intake systems. 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. AEM Cold Air systems relocate the filter outside of the engine compartment for a cooler intake charge and more power over the rpm range. 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 or pending exemption (50 state legal) and come with complete installation hardware, comprehensive instructions, AEM decal and license plate frame.To avoid the possibility of introducing water into the intake system and hydrolocking your engine, the use of the AEM Air Bypass Valve is highly recommended.
