A cold air intake is a special type of intake that draws cooler air into the engine. In simple terms, Fuel + Oxygen + Spark = Combustion, and increasing any (or all 3) of these variables can create additional horsepower at the wheels. The principal is that since cooler air is denser (more oxygen in the same amount of space), more oxygen enters the engine, and creates a stronger combustion. It is also said that increasing the amount of oxygen can create a more complete combustion, gaining a bump in fuel efficiency and gas milage. There are dozens of cold air intakes on the market specifically for the Civic Si.
Good Cold Air Intakes for the Civic Si
AEM: This is probably the best cold air intake out there. AEM offers two versions, the regular AEM Cold Air Intake, and one that they call The V2 Cold Air Intake. Dyno testing suggests that these intakes can provide a boost of about 1-5 horsepower.
Injen: Injen makes excellent intakes for a wide variety of vehicles, including the Civic Si. Installing one of these is a sure-fire way of increasing your horsepower and torque. Dyno testing also confirms that 1-5 extra horsepower can be yours by installing an Injen Cold Air Intake.
Please note: The above air intakes are completely safe, legal, and high quality. I cannot vouch for any of the other cheaper brands that you're sure to find on eBay. Do your homework before buying a cold air intake, and always remember: "Buyer beware" and "You get what you pay for". Don't complain when your check engine light comes on because you wanted to save a few bucks on an intake. Thanks.
