AEM Cold Air Intake System For Subaru WRX 2022-2023 H4 2.4L F/I Turbo P/N 21-891C
Description

The AEM Cold Air Intake System for Subaru WRX 2022ƒ??2023 with the 2.4L H4 Turbo engine (P/N 21-891C) is engineered to improve engine breathing by replacing the restrictive factory air intake system. Designed, tuned, and dyno-tested to increase horsepower and torque, this system delivers noticeable performance gains and a more aggressive engine sound. Air is drawn in through a large AEM Dryflow synthetic air filter, which offers excellent airflow and filtration without the need for oil. The mandrel-bent aluminum intake tube features a durable gunmetal gray powder-coated finish, and the included custom heat shield with lid protects the filter from engine heat. Backed by AEMƒ??s Lifetime Limited Warranty, this intake system offers performance, durability, and ease of maintenance for serious enthusiasts.

Key Features:

  • Designed for Subaru WRX 2022ƒ??2023 (2.4L H4 Turbo): Direct replacement for factory air intake system.

  • Dyno-Tested Performance Gains: Increases horsepower and torque across the RPM range.

  • Oversized AEM Dryflow Air Filter: Washable, oil-free synthetic media with extended service life.

  • Mandrel-Bent Aluminum Intake Tube: Ensures smooth airflow and features a durable gunmetal gray powder-coated finish.

  • Custom Heat Shield with Lid: Protects the filter from engine heat for consistent performance.

  • Long Service Interval: Filter can go up to 100,000 miles before cleaning (depending on conditions).

  • Easy Installation: Designed for a straightforward install using basic hand tools.

  • Warranty: Backed by AEMƒ??s Lifetime Limited Warranty.

  • Emissions Note: Not legal for sale or use in California and other states adopting California emission standards (check local laws).
