The AEM 21-820DS is an innovatively designed intake system to completely replace the restrictive air filter and airbox of some Infiniti QX30 models. The airbox has been crafted with premium materials and designed with 2 air scoops that feed from factory vent locations. It is aerodynamically engineered for better airflow, heat resistance, and improved aesthetics under the hood. The ECU is relocated underneath the airbox where a large vent keeps it cool. To clear the hood stand we incorporate a channel groove for a factory look on the air box. The AEM logo is showcased in a transparent badge, which also serves as a window to the filter so you know when it is time to have it serviced. The cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.
