In April of 1999, the Honda Motor Company officially launched the Honda S2000 roadster. The S2000 was created to celebrate the company's 50th anniversary. The S2000 served a dual purpose to Honda as a celebratory icon as well as a tribute to the company's first production car; the S500 sports car.

The S2000 has undergone several changes and upgrades since its origin. Starting with the 2006 model year, the S2000 comes powered by a 2.2-liter, inline, four-cylinder (F22C1) engine. Known as the "second generation" or "AP2" model, the S2000 is more powerful and fun to drive than ever before. To give S2000 owners even more to celebrate about, AEM has released the 21-690 Cold Air Intake System for the 2006-2009 Honda S2000.

Available in two finishes, the 21-690 Cold Air Intake system comes in either a gunmetal gray finish (21-690C) or a polished finish (21-690P). The 21-690 Cold Air Intake is constructed in a three-piece design using high-quality aluminum intake piping. Originating at the S2000's throttlebody, the 21-690 intake system relies on a series of mandrel bent curves to reach the vehicle's front bumper where the DryFlow Performance Air filter is located. By mounting the DryFlow air filter in the front bumper of the S2000, the best source for cool air inlet temperatures is attained.

The S2000's performance is vastly improved with the AEM 21-690 cold air intake system in place rather than the restrictive factory air intake components. As tested on a 2008 Honda S2000, AEM was able to realize a maximum gain of 7.67 horsepower at 7,300 RPM. Installation takes 90 minutes or less using basic tools.

The 21-690 Cold Air Intake System for the S2000 uses a 21-2113DK DryFlow Performance air filter. The 21-2113DK has a 3.25-inch (83mm) inlet diameter and a height of 7-inches (178mm) allowing abundant airflow into the S2000's F22C1 engine. The oil-free DRYFLOW technology is extremely durable and easy to clean. To further augment the filtration properties of the DryFlow performance filter, AEM also offers DryFlow Pre-Filters (Part number 1-4007 for the 21-690 intake system). Designed to prevent splashes of water and/or mud from saturating the DryFlow air filter, AEM's Pre-Filters are manufactured from durable micro-screen materials that are pretreated with a proprietary hydrophobic process.
