Product Description

The AEM 21-877C is a Cold Air Intake System for the 2019-2026 Mazda 3 with the naturally aspirated 2.5L Skyactiv-G L4 (FWD and AWD, Sedan and Hatchback). Designed, tuned, and dyno-tested specifically for this application, the system replaces the restrictive factory airbox with a mandrel-bent aluminum tube finished in gunmetal gray powder coat, routing air through an oversized AEM Dryflow oil-free synthetic filter for improved airflow and measurable horsepower and torque gains. The custom heat shield with lid reduces intake air temperatures for consistent performance.

The AEM Dryflow filter requires cleaning only every 100,000 miles under normal conditions. Accommodates the factory MAF sensor and all OEM emissions control devices for a clean bolt-on installation. Does not fit 2.5L Turbo models -- see AEM 21-884C for turbo applications. Not legal for sale or use in California. Backed by AEM's Lifetime Limited Warranty.
