Tired of all the keyboard warriors on the internet arguing about what intake makes the most power? So are we, and it’s time to cut through the noise. This article puts three popular intake styles to the test on a 2018 Chevy Silverado: the new K&N NextGen, a closed box competitor, and a discount open airbox competitor. Using airflow, dyno, and track tests, we measure real-world performance to find out what intake is best!
See how K&N gives you the most Horsepower on a stock tune with proven dyno results to give your vehicle power you can hear and feel. Upgrade to a K&N Cold Air Intake or K&N Air Filter for enhanced vehicle performance, cost savings, and superior engine protection with easy maintenance and long-lasting durability. Experience the benefits of improved airflow and protection, backed by a lifetime limited warranty.

Designed to be compatible with 2017-2018 Honda Civic Type R models, the AEM® 21-832C air intake system is precision engineered to increase horsepower and torque—and features a low-restriction, synthetic DRYFLOW® air filter to help protect against damaging engine contaminants.
AEM® COLD AIR INTAKE SYSTEMS CAN INCREASE HORSEPOWERIf you want to give your Type R more punch, check out the 21-832C performance air intake system, designed for 2017-2018 Civic Type Rs. The 21-832C is engineered to help keep engine air moving into the throttle body cooler (which can increase engine combustion efficiency) by providing a smoother, less restrictive path for airflow. Many stock intake systems incorporate components that create turbulence/heat, which can decrease your engine’s performance. By replacing your factory system with a specially designed tube and less restrictive filter, your engine can get the performance boost it craves.
AERODYNAMIC INTAKE TUBE INCREASES AIRFLOWMany factory intake systems force air through a high-restriction disposable paper air filter, and a complicated system of tubing that can cause air to swirl and become turbulent. Because turbulence creates heat—which reduces the density of oxygen molecules in the air—your engine may not be able to combust as efficiently as it could with cooler air available. An aerodynamic AEM intake tube helps keep engine air cooler, and often significantly increases engine combustion efficiency.
The 21-832C intake system features an aerodynamic, mandrel-bent aluminum intake tube, which is engineered to reduce turbulence in the air and help keep the airflow oxygen-dense. The 21-832C also incorporates a steel heat shield, which helps protect the air filter and intake air from high engine temperatures. DRYFLOW® FILTER OFFERS EXCEPTIONAL PROTECTIONThe included oil-free DRYFLOW® air filter is composed of a 3D synthetic filtration media that is washable and reusable, and provides outstanding airflow to your engine. Precision engineered to increase horsepower, the oil-free media can last up to 100,000 miles before cleaning is required (under normal highway driving conditions). Instead of re-purchasing a new disposable filter every 20,000-30,000 miles, you can simply clean and reuse your long-life AEM DRYFLOW® filter! INSTALLATIONThe AEM 21-832C intake system is engineered to incorporate factory mounting points and the factory mass air sensor. Installation can typically be completed in 90 minutes or less, and requires only simple hand tools. Detailed instructions are included in your kit. Engineered to fit:
• 2017 Honda Civic Type R 2.0L L4 F/I All Models • 2018 Honda Civic Type R 2.0L L4 F/I All Models WARRANTYThe 21-832C is protected by AEM’s Lifetime Limited Warranty. Using an AEM replacement air intake system will not void your factory warranty; in the U.S., manufacturers must provide evidence that an aftermarket part is the cause of a necessary repair in order to void or deny warranty coverage. The Consumer Products Warranty Act of 1975 (also known as the Magnuson-Moss Warranty Act) protects consumers’ rights to their warranty coverage.
DYNAMOMETER RESULTSDuring dynamometer testing, a 2017 Honda Civic Type R 2.0L turbo with a factory air intake system was recorded at 263.2-horsepower at 4,945 RPM. After installation of 21-832C, the same vehicle was recorded at 280.3-horsepower at 4,945 RPM—an estimated increase of 17.1-horsepower. The torque also increased from 256.0 lb.-ft. to 269.7 lb.-ft.—an estimated increase of 13.7 lb.-ft. at 3,765 RPM. Horsepower gains vary among products and applications, but each AEM performance air intake system is designed to increase airflow for specific vehicles and their engines. Each kit undergoes rigorous testing to help ensure that the filter and intake tube are engineered to deliver large increases in airflow and horsepower.
