It's no secret that AEM has been the preferred performance intake manufacturer among Honda and Acura enthusiasts for nearly two decades. Why mess with the best? AEM's 90-93 Acura Integra Cold Air Intake systems are built from CNC mandrel-bent 6061 piping and tuned in both length and diameter to maximize power for each application. Computer TIG-welded fittings and brackets ensure solid construction and durability for years to come. For filtration, AEM utilizes its new reusable lightweight urethane, four-layer cotton-gauze filter that features a redesigned air horn for improved performance. Each intake that rolls off the line at the AEM factory is available with show quality powder coating or mirror polished finish, so you know its gonna look great when you pop the hood. All Integra cold air intake systems are C.A.R.B. exempt or pending exemption (50 state legal) and come with complete installation hardware and comprehensive instructions.
