AEM 2015-2021 Subaru WRX 2.0L H4 F/I - Cold Air Intake System

The AEM 21-732C Performance Cold Air Intake System enhances horsepower and torque by replacing your vehicle's factory air filter and intake housing. Specifically designed, tuned, and dyno-tested for Subaru WRX models, it features an oversized AEM Dryflow synthetic washable air filter for superior airflow, filtration, and performance. The air filter is housed in the original air box space and shielded by a heat shield, reducing intake air temperature for increased horsepower.

The intake tubing of this system is crafted from mandrel-bent aluminum with a robust gunmetal gray powder-coated finish. Developed to accommodate the engine's factory emissions control devices, including the mass air flow sensor, it ensures optimal performance. Featuring a tapered cylinder-shaped AEM Dryflow air filter made from oil-free synthetic media, this system lasts up to 100,000 miles before cleaning (depending on driving conditions). Installation is hassle-free with commonly available tools, backed by AEM's Lifetime Limited Warranty. Please review vehicle applications for legal compliance.
