AEM Cold Air Intake System - 2013–2020 Subaru BRZ / 2013–2016 Scion FR-S / 2017–2020 Toyota 86

The AEM 21-853C replaces the factory intake assembly on supported first-generation BRZ, FR-S and Toyota 86 applications. It combines a gunmetal gray aluminum tube with a reusable Dryflow filter and a shaped heat shield.

Design and operation

The mandrel-bent tube provides a smooth air path. Protective edge trim lines the heat shield, which helps separate the filter from surrounding engine-bay heat. The verified tube finish is gunmetal gray, rather than polished.

Key specifications

• Manufacturer part number: 21-853C
• Gunmetal gray aluminum tube; heat shield with edge trim.
• Washable, reusable, oil-free synthetic Dryflow filter.
• Replacement filter: 21-204DK.

Installation and compatibility

Check each model’s individual year range and trim. Shared platform architecture does not establish compatibility with later-generation BRZ or GR86 vehicles. Follow the installation instructions and confirm calibration compatibility with the vehicle’s existing modifications.

Maintenance

Inspect the filter according to dust exposure and use. Clean it with a cleaner suitable for the Dryflow media, allow it to dry fully and do not apply filter oil. Check clamps and connections during routine servicing.

Important application notes

CARB EO D-670-25 applies only to covered applications. Do not assume every year and trim in the fitment list has identical emissions eligibility.

Vehicle fitment

The following catalog applications include trim-specific year ranges. Confirm the exact vehicle before ordering; listed fitment does not by itself establish emissions approval.
