This AEM Performance Air Intake System lets a 2018-2026 Subaru Forester 2.5L F/I breathe more freely than the restrictive factory air intake housing allows, and is designed, tuned, and dyno-tested to produce more horsepower and torque. The cone-shaped AEM Dryflow air filter uses an oil-free synthetic media good for up to 100,000 miles before cleaning under normal driving conditions. A custom-shaped heat shield with edge trim lining keeps engine bay heat away from the intake, and the tube is mandrel-bent aluminum with a durable gunmetal gray powder coat finish. Backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50-state legal; refer to the vehicle applications below to determine legal status for a specific vehicle.
