The AEM 21-686C Cold Air Intake System is engineered specifically for the Honda Civic models from 2006 to 2011 equipped with a 1.8L 4-cylinder engine. This system replaces the factory air intake components, allowing for improved airflow and enhanced performance characteristics.
By utilizing an oversized AEM Dryflow synthetic washable air filter, the 21-686C significantly enhances airflow and filtration efficiency. The filter is strategically placed above the driver's side wheel well, which aids in reducing intake air temperature, contributing to an estimated horsepower gain of 4 HP at 3800 RPM.
The intake tubing is constructed from mandrel-bent aluminum, finished in a durable gunmetal gray powder coat. This not only provides a sleek aesthetic but also ensures longevity against the elements. The system is designed to integrate seamlessly with the vehicle's factory emissions control devices, including the mass air flow sensor and PCV hose.
The AEM 21-686C Cold Air Intake System comes complete with all necessary mounting hardware and requires no additional filter oil, making maintenance straightforward. The washable air filter can last up to 100,000 miles under normal driving conditions before needing cleaning.
This intake system is street legal in all US states, including California, under the specified CARB EO number. Ensure to verify the legal status for your specific vehicle application.
California Air Resources Board Exempt: Yes; CARB EO: D-670-21

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.
