The AEM Performance Cold Air Intake for Subaru WRX and WRX STI (fits 2008–2011 WRX/STi and related Impreza models) replaces restrictive factory plumbing with mandrel-bent aluminum tubing and an oversized Dryflow oil-free synthetic filter housed behind a heat shield to reduce intake temperatures. Tuned and dyno-tested for specific Subaru applications, it offers washable reusable filtration, a textured red powder-coat finish, straightforward installation with common tools, and is backed by AEM's lifetime limited warranty.
