AEM Wrinkle Red Cold Air Intake Subaru WRX / STI 2008-2014

The AEM 21 - 478WR Cold Air Intake System is a game - changer for your Subaru. It boosts horsepower and torque by swapping out your vehicle's restrictive factory air filter and intake housing. This system is custom - designed, tuned, and dyno - tested to fit specific Subaru WRX, WRX STI, Impreza WRX, and Impreza WRX STI models. Air flows in through an oversized AEM Dryflow synthetic washable air filter, delivering excellent air flow, filtration, and performance. The air filter sits in the original air box space and is shielded by a heat shield that cuts down intake air temperature and ups the horsepower. The intake tubing is made of mandrel - bent aluminum with a tough, textured red powder - coated finish. It's designed to work with the engine's factory emissions control devices, including the mass air flow sensor. The cylinder - shaped AEM Dryflow air filter uses an oil - free, synthetic filter media that can last up to 100,000 miles before cleaning (depending on driving conditions). Installation is a breeze with common tools, and it comes with AEM's Lifetime Limited Warranty. Note that some AEM air intakes aren't legal in California and other states with California emission standards, while others are legal in all 50 states. Check the 21 - 478WR vehicle applications to find the legal status for your car. Part #: 21 - 478WR
