AEM Cold Air Intake System 21-808C for Subaru 2.5L 4-Cyl 2015-2016 Legacy Outback
$399.99

If you’re looking to give your Subaru a little extra kick, the AEM 21-808C Performance Cold Air Intake System is a solid choice. This isn’t just about adding a flashy filter; it’s about real gains in horsepower and torque. The whole setup is designed to improve airflow and pull in cooler, denser air, which is key for performance. The heart of this system is the cone-shaped AEM Dryflow filter. It’s made from a synthetic material that not only boosts airflow but also keeps things clean and efficient. Plus, you won’t have to deal with oiling it—just pop it in and forget about it for up to 100,000 miles, depending on how you drive.

One of the standout features is the way the air filter is positioned. By relocating it lower and closer to the front, you’re tapping into that cooler air, which makes a noticeable difference. A heat shield is included to keep the intake air from getting too hot from the engine, which is a nice touch. The intake tube is made from aluminum and has a sleek gunmetal gray powder coat. It’s mandrel-bent, which means it’s designed to minimize airflow restriction as the air travels to the throttle body. You’ll be swapping out the restrictive factory pipe and air intake housing for this system, and trust me, the installation is straightforward. Instructions are included, and it’s pretty much a plug-and-play deal.

What Is an AEM Cold Air Intake System?

An AEM cold air intake system is specifically designed to increase the volume of cold air flowing into your engine as you drive. The thinking behind this is that cold air is much denser than warm air. Therefore, if there is more cold air in your engine, there is more air in general, which also means that there is more oxygen. A higher amount of oxygen present in a car engine increases the potency of combustion, which can increase the power and efficiency of your engine.

What Are the Benefits of an AEM Intake System?

An AEM intake kit maximizes the amount of power you can get from your engine. This increase in power will also help you conserve fuel and increase your fuel efficiency, saving you money at the gas station. In a sense, an AEM intake system helps your car and engine “breathe” more efficiently, allowing it to reach its full potential.

Why Should I Choose an AEM Intake Kit?

AEM is regarded as one of the best aftermarket intake systems on the market, combining quality materials, cutting-edge technology and reliable design to help drivers around the globe improve the power of their engine. All AEM cold air intake systems are engineered to increase your car’s torque and horsepower, and any AEM intake kit comes with a lifetime limited warranty.
