AEM 21-889C Gunmetal Gray Cold Air Intake System for 2019-2021 Nissan Altima (L4-2.0L)

Fits 2019-2021 Nissan Altima models including Edition ONE, Platinum, and SR (L4-2.0L Turbo).

The AEM 21-889C Cold Air Intake System is engineered to increase horsepower and torque by replacing the restrictive factory air filter and intake housing with a high-flow, tuned induction system. This intake features a mandrel-bent aluminum intake tube with a durable gunmetal gray powder-coated finish, designed to maintain smooth, laminar airflow into the turbocharger for improved throttle response.

The system utilizes an oversized AEM Dryflow synthetic air filter. This oil-free, washable media provides exceptional filtration and can go up to 100,000 miles before cleaning is required under normal driving conditions. An integrated heat shield is included to isolate the air filter from engine bay heat, ensuring cooler, denser air enters the engine for more efficient combustion.

• Direct Fit: Specifically designed to accommodate factory emissions control devices, including the mass airflow (MAF) sensor and breather tube.
• Premium Construction: Mandrel-bent aluminum tubing prevents airflow bottlenecks.
• Dryflow Technology: Oil-free synthetic filter media is easy to maintain and preserves airflow efficiency.
• Installation: Straightforward bolt-on installation using factory mounting points and common hand tools.
• Finish: Gunmetal gray powder coating for long-term corrosion resistance.
• Manufacturer Part Number: 21-889C
