Overview

The AEM 21-874C is a cold air intake system designed for the 2018-2019 Subaru Forester 2.5L F/I. It allows the engine to breathe more air than the stock intake, potentially increasing horsepower and torque. The system features an aluminum, mandrel-bent intake tube with a gunmetal gray powder coat finish and a red, cone-shaped AEM Dryflow air filter made from synthetic media.
Show original supplier description
The AEM 21-874C Cold Air Intake System is designed to replace your vehicle's restrictive factory air intake housing, allowing the engine to breathe more freely. This system is custom-engineered, tuned, and dyno-tested to maximize horsepower and torque, while also improving acceleration and engine sound. The intake tube is constructed from mandrel-bent aluminum with a durable gunmetal gray powder-coated finish, promoting smooth airflow. It includes a cone-shaped AEM Dryflow air filter made from an oil-free, synthetic media that requires cleaning only every 100,000 miles, depending on driving conditions. A custom heat shield with edge trim lining is also included to prevent engine bay heat from entering the intake. This system is backed by AEM's Lifetime Limited Warranty and is proudly manufactured in the USA. It comes complete with all necessary mounting hardware and installation instructions. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards; please check vehicle applications to determine the legal status for your specific vehicle.
