Description

The AEM 21-878DS is a performance cold air intake system designed for Nissan Altima models with a 2.5L L4 gas engine. This system features low-restriction intake tubing made from mandrel-bent aluminum to increase air velocity and high-volume airflow for maximum performance gains. It includes a custom-shaped heat shield with a lid to help deliver cool air outside the engine compartment.

The intake is equipped with an AEM Dryflow™ air filter, which does not require oil.
