AEM Cold Air Intake System for Nissan Altima 2019ƒ??2024 (L4 2.5L F/I)

Enhance the performance of your Nissan Altima with the AEM Cold Air Intake System, engineered for 2019ƒ??2024 models featuring the 2.5L inline-4 fuel-injected engine.

The intake tube is crafted from mandrel-bent aluminum with a durable silver powder-coated finish and is paired with a custom-shaped heat shield with lid to protect from engine heat. Designed for long-lasting performance, the filter can be used for up to 100,000 miles before cleaning is needed, depending on driving conditions. This system is backed by AEMƒ??s Lifetime Limited Warranty.
