AEM Induction 21-823DS Cold Air Intake System for Infiniti M37 and Q70 3.7L V6

The AEM 21-823DS is a twin intake system designed for some Infinity Q70 models. The factory layout of this vehicle has individual throttle bodies for each bank of cylinders so each side has its own air intake system. This AEM air intake system replaces both the left and right factory air box, tube, and filter. This system includes the heat shield, intake tube, and AEM dryflow air filter on both left and right sides. The cone shaped AEM Dryflow air filters are 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). Both factory MAF sensors mount directly on the intake tube. The heatshield also has a rubberized edge trim to better isolate air from engine bay heat. 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.
