Show original supplier description
The AEM Cold Air Intake (21-891C) is a performance-oriented upgrade designed to replace the restrictive factory intake on your 2022+ Subaru WRX. This system allows your engine to breathe more air, leading to increased horsepower and torque, as well as sharper turbo and throttle response. The intake features a mandrel-bent aluminum intake pipe with smooth walls to minimize turbulence and maximize airflow velocity. It includes an oversized AEM Dryflow synthetic washable air filter, which is oil-free and can last up to 100,000 miles before cleaning is needed, depending on driving conditions. A custom-shaped heat shield with a lid is also provided to protect the filter from the heat of the engine bay, ensuring cooler air intake temperatures. This AEM cold air intake system is precision-tuned and dyno-tested to ensure optimal performance gains. It is backed by AEM's Lifetime Limited Warranty. Please note that some AEM air intakes are not legal for sale or use in California.

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
