The infamous Honda Civic… this car has been around for as long as most of
us can remember. Honda first introduced the Civic as a two-door coupe in the
early 70’s and ever since its release the Civic has been one of the best-selling
compact cars of all time. Fast-forward almost 40 years and the Civic attracts a
variety of drivers. You can see the Civic being driven by anyone from young
adults that recognize its sporty side to elderly folks that want a car with good
Cold Air Intake System for 2006-2011 Honda Civic with the 1.8L engine with
Gunmetal Gray Finish.
AEM 21-686P Cold Air Intake System for 2006-2011 Honda Civic with the 1.8L
engine with polished finish.
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.
21-686C and 21-686P increased horsepower by 4 HP @ 3,800 RPM
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
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.
