AEM Performance Cold Air Intake System for Subaru Legacy

Unlock hidden horsepower and torque with the AEM Performance Cold Air Intake System, specifically designed for the 2017-2018 Subaru Legacy equipped with the H4-2.5L F/I engine. This intake system replaces your vehicle's restrictive factory air filter and intake housing, allowing for significantly improved airflow and a more aggressive engine sound. AEM's commitment to performance is backed by rigorous dyno-testing to ensure maximum gains for your specific application.

Engineered for Performance:

  • Horsepower & Torque Gains: Designed and tuned to deliver noticeable increases in power output.
  • Oversized Dryflow Filter: Features an AEM Dryflow synthetic washable air filter for excellent filtration and unrestricted airflow.
  • Heat Shield: Includes a heat shield to reduce intake air temperature by insulating the filter from engine heat, further boosting horsepower.
  • Mandrel-Bent Aluminum Tube: Constructed from high-quality, mandrel-bent aluminum tubing with a durable gunmetal gray powder-coated finish for a sleek look and optimal flow.
  • Vehicle Specific Design: Engineered and dyno-tested to fit specific Subaru Legacy models, ensuring proper integration.
  • Emissions Compliance: Designed to accommodate factory emissions control devices and the mass airflow sensor.

The AEM Cold Air Intake system works by drawing cooler, denser air from outside the engine bay, which leads to more efficient combustion and increased power. The washable Dryflow air filter means no oiling is required, simplifying maintenance and ensuring consistent performance. The gunmetal gray finish on the aluminum intake tube adds a custom, high-performance look under the hood.

Installation is designed to be straightforward, utilizing the original air box space and factory mounting points.
