Brand New AEM® Intake System for 2017-2018 Honda Civic Type R

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.

If 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.

Many 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.

Gain an estimated 17.1 horsepower with the 21-832C intake system

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.


The 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!


The 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.

The 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.

During 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.

Blušs claimed his first-ever Formula Drift win on May 12, edging out Fredric Aasbo—the most winningest driver in FD history—and Chris Forsberg, a three-time FD Championship winner who has also claimed the most podium finishes in FD history.

The competition this season is tighter than ever, with remarkably close point margins within the top 12. Blušs had to fight hard for his first FD win—battling against Kevin Lawrence, Forrest Wang, James Deane, and Piotr Wiecek before finally defeating Fredric Aasbo for the top spot on the podium. “Atlanta was a rollercoaster for me and the team,” he commented. “Through numerous One More Times, we fought hard to the very end. Thanks to AEM® Intakes for supporting us this round and throughout the season.”

Blušs, originally from Latvia, began his Formula Drift career in 2015 and currently races for HGK Motorsports. He pilots the BMW E92 Eurofighter—complete with a custom carbon kevlar body—powered by a 7.0-liter V8 engine that provides 900-horsepower. The car features a custom AEM® Intakes panel filter, which utilizes the same technology available in the AEM® Dryflow® Air Filters—available for your vehicle at Blušs has great confidence in his AEM® products. “The service, the quality, and the performance are perfect,” he commented.

The Eurofighter wasn’t originally intended to hit the drifting track so soon—oddly enough, it was intended to appear at the AEM® Intakes display booth at Irwindale 2017 instead of in the competition—but it hit the pavement as a pinch hitter after a major mechanical issue forced the HGK team to sideline the BMW E46 Blušs had intended to pilot. The Eurofighter has continued to prove its mettle as a powerful competition vehicle this season.

Fredric Aasbo continues to lead the pack with 260 points—with Forsberg a close 37 points behind. Blušs commands 174 points—87 points behind the top position. If the competition continues to be as close as it was at Road Atlanta, Round 4 will be an event not to miss.

You can see Blušs compete in Round 4 of the Formula Drift Pro Series at Wall Stadium Speedway in Wall Township, New Jersey on June 1-2.
