AEM's Performance Cold Air Intake Systems are tuned and dyno-tested to give your engine more power and acceleration by replacing the restrictive factory air filter, air intake tubing and air box assembly.
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.
- Precision-tuned and dyno-validated to enhance throttle response, sharpen acceleration, and improve overall engine efficiency, helping maximize horsepower and drivability.
- Creates a deeper, more aggressive induction tone that highlights the intake system’s improved airflow.
- Features low-restriction intake tubing that increases air velocity and high-volume airflow for maximum performance gains.
- Equipped with a long-life, high-capacity air filter capable of up to 100,000 miles before servicing (depending on driving conditions), reducing maintenance while maintaining strong, clean airflow.
- Utilizes washable, reusable, oil-free synthetic filter media that preserves airflow efficiency, traps harmful contaminants, and provides long-term value over disposable filters.
