AEM 21-478WR Wrinkle Red Cold Air Intake, Subaru WRX/STI 2008-2014

Description

21-478WR is an AEM Wrinkle Red Cold Air Intake for Subaru WRX/STI 2008-2014. It replaces the restrictive factory air filter and intake housing to free up horsepower and torque.

AEM designs, tunes and dyno tests each cold air intake for its specific vehicle application.

Air enters through an AEM Dryflow air filter made from an oil-free synthetic media that is washable and reusable. The filter can go up to 100,000 miles between cleanings, depending on driving conditions. The filter is located in the original air box space. A heat shield helps keep engine bay heat away from the intake.

The intake tube is mandrel-bent aluminum with a wrinkle red powder coated finish. The system is built to work with the engine's factory emissions control devices.

Some AEM intakes are not legal for sale or use in California and other states that have adopted California emissions standards, while others are 50 state legal. Check AEM's vehicle application listing for 21-478WR to confirm the status for your vehicle.
