Well, a small displacement engine such as the Civic’s 1.8-liter four cylinder that gets good gas mileage (~29 MPG) often leaves the driver with a desire for more power. In the case of the Civic, there happens to be additional horsepower ready to be unleashed. AEM recognized the car’s need for an air intake system and designed a Cold Air Intake System for the 2006, 2007, 2008, 2009, 2010, and 2011 Honda Civic with the 1.8-liter engine. This cold air intake comes in two finishes. Part number 21-686C has a gunmetal finish and part number 21-686P has a polished finish. During the design phases, AEM was able to not only design a more efficient air intake system that looks and sounds great, the design also added significant horsepower to the 1.8-liter powerplant.
This AEM Cold Air Intake System completely replaces the restrictive factory intake system of the Honda Civic. By replacing the factory airbox and air filter with a mandrel-bent aluminum intake tube that optimizes airflow and filtration more power was gained. AEM’s dyno tests have recorded a 4 horsepower increase at 3,800 RPM on the 2006-2011 Honda Civic 1.8L. This increase in horsepower brings the stock baseline power of 98 wheel horsepower up to 102 wheel horsepower with the AEM Cold Air Intake System installed.
The 21-686C and 21-686C intakes route an AEM Dryflow 21-201DK air filter in the wheel well where the air filter can draw cool air safely. The 21-201DK air filter features a flange inside diameter of 2.5-inches (64mm) and an overall height of 5.125-inches (130mm). The oil-free DRYFLOW technology is extremely durable and easy to clean.
