This AEM Performance Air Intake System lets a 2019-2026 Nissan Altima L4-2.5L F/I breathe more freely than the restrictive factory air intake housing allows, and is designed, tuned, and dyno-tested to produce more horsepower and torque. Air enters through an oversized, tapered AEM Dryflow synthetic washable filter for outstanding airflow, filtration, and performance. The intake tube is mandrel-bent aluminum with a durable silver powder coated finish, and a custom-shaped heat shield with lid is included. The oil-free Dryflow filter runs up to 100,000 miles before cleaning under normal conditions. Backed by AEM's Lifetime Limited Warranty.
