AEM Polished Cold Air Intake Subaru Legacy GT 2005-2009

The AEM 21 - 475P Performance Cold Air Intake System is a game - changer for your Subaru Outback XT and Legacy GT. It boosts horsepower and torque by swapping out your vehicle's restrictive factory air filter and intake housing. Specifically designed, tuned, and dyno - tested for these models, this system takes in air through an oversized AEM Dryflow synthetic washable air filter. This filter offers excellent air flow, top - notch filtration, and great performance. Located in the original air box space and shielded by a heat shield, it reduces intake air temperature and ups the horsepower. The intake tubing is crafted from mandrel - bent aluminum with a durable chrome - like finish. It's also designed to work with the engine's factory emissions control devices, including the mass air flow sensor. The tapered cylinder AEM Dryflow air filter is made of oil - free synthetic media, lasting up to 100,000 miles before cleaning (depending on driving). Easy to install with common tools and backed by AEM's Lifetime Limited Warranty. Note that some AEM air intakes aren't legal in California and states with similar emission standards, while others are 50 - state legal. Check the 21 - 475P vehicle applications for legal status.
