Description
AEM 21-889C is an application-specific cold air intake for 2019-2021 Nissan Altima 2.0L Turbo. It replaces restrictive factory intake components to provide a revised airflow path to the engine.
The filter uses a heat shield to help separate it from engine-compartment heat. Shielding and filter location are important considerations when comparing this system with an unshielded open-filter intake.
Technical Highlights
- Heat-shielded filter arrangement.
- Mandrel-bent aluminum intake tubing.
- Tube finish: Gunmetal gray.
- Washable AEM Dryflow synthetic air filter.
- Oil-free filter media; no filter oil is required after cleaning.
- Provisions for mass airflow sensor.
Installation & Compatibility
Confirm engine, trim, sensor arrangement, and the applicable fitment entries before ordering. Install all retained factory connections and check for air leaks before operation. Inspect the filter according to operating conditions; dusty environments and track use can require more frequent service. Emissions eligibility depends on the exact vehicle application; do not assume approval from the intake family name.
