AEM Cold Air Intake Gunmetal Subaru WRX 2015-2021

The AEM 21 - 732C Performance Cold Air Intake System is a game - changer. It boosts horsepower and torque by replacing your car's restrictive factory air filter and intake housing. Specifically designed, tuned, and dyno - tested for certain Subaru WRX models. Air flows in through an oversized AEM Dryflow synthetic washable air filter, delivering excellent air flow, filtration, and performance. The filter sits in the original air box space and is shielded by a heat shield to lower intake air temperature and increase power. The intake tubing is made of mandrel - bent aluminum with a tough gunmetal gray powder - coated finish. This system is developed to work with the engine's factory emissions control devices, including the mass air flow sensor. The tapered cylinder AEM Dryflow air filter uses oil - free synthetic media and can last up to 100,000 miles before cleaning (depending on driving). It's easy to install with common tools and comes with 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 - 732C vehicle applications for each vehicle's legal status. Part #: 21 - 732C

Using this AEM cold air intake is a breeze. First, gather some common tools and start the installation process. It fits right into the original air box space of your Subaru WRX 2015 - 2021. When it comes to using it, just drive as you normally would and enjoy the extra horsepower and torque. As for maintenance, the AEM Dryflow air filter is great. You don't have to clean it often - it can go up to 100,000 miles before needing a clean, but this depends on your driving conditions. When you do clean it, follow the cleaning instructions provided. Also, make sure to check the legal status of this air intake in your state. Some areas, like California and those with similar emission standards, may have restrictions, so always check the vehicle applications to stay on the right side of the law.
