The AEM-21-774DS Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle’s restrictive factory air filters and air intake housings. This air intake system was designed, tuned and dyno-tested to fit select Infiniti Q50 models. Air enters the system through dual AEM Dryflow synthetic washable air filters for outstanding air flow, filtration and performance. The air filters are located in the original air box spaces and are protected by heat shields which are designed to reduce intake air temperature and increase horsepower. Air is then fed to the engine through not one, but two air intake tubes. This air intake system was developed to accommodate the engine’s factory emissions control devices including the mass air flow sensors and crankcase vent tube. The dual tapered cylinder 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). The air intake system is easy to install with commonly available tools and it 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.
