  • Power Gains: Tuned and dyno-tested to deliver measurable increases in horsepower and torque.
  • Heat Shielding: Includes a custom-shaped heat shield with edge trim to effectively block hot engine bay air from entering the intake.
  • Premium Materials: The intake tube is crafted from mandrel-bent aluminum with a durable gunmetal gray powder-coated finish.
  • Low Maintenance Filter: The oil-free Dryflow filter offers up to 100,000 miles of use before cleaning is needed, depending on conditions.
  • Extensive Fitment: Designed for a wide range of Subaru models including 2017-2023 Impreza (Base, Limited, Premium) and 2018-2024 Crosstrek (Base, Hybrid, Limited, Premium).

This AEM Cold Air Intake system is backed by AEM's Lifetime Limited Warranty. Please be aware that some AEM intakes may not be legal for sale or use in California and other states that follow California emissions regulations.
