One of the best brands for performance intakes would be K+N. These intakes, however, make very minimal difference to a four cylinder vehicle. These engines have been designed to produce as much power as possible due to the fact that they have to compete with larger engines that make power more easily. I would say that the recommended intake for this vehicle would be the one that came with it from the factory. However, adding an intake system should have no effect on the vehicle’s ability to pass an emissions test. This is because air goes in through the intake and emissions come from the exhaust.

K&N – Cold Air Intake: Adds Up To 3 Horsepower, With Million Mile Air Filter (Part No. 63-3517)
Gain 29 horsepower, 25 torque. No tuning required. Aggressive engine growl during acceleration. This product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles.
AEM Honda cold air intakes are a simple way to add performance and great looks to your vehicle. Cold air intakes are available for the Honda models shown below.
The seventh-generation North American Civic DX/LX/Value Package (VP) engines were the last Hondas not to use the company`s variable valve time system (VTEC); the second to last was the 1996-2004 Acura 3.5RL.
A larger combustion = more power. Cold Air Intakes are said to improve your vehicle`s performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn`t enough power to put you back in your seat, it will give your car or truck a little pep in its step.
While it varies from vehicle to vehicle and by company, most cold air intake systems may add around 5 to 20 additional horsepower to your vehicle.
For those putting a cold air intake on a 4-cylinder engine, an improvement of up to 20 additional horsepower can be seen. Cold air intake makes a significant difference.
Installing a brand-new air intake will help the engine suck in more oxygen-rich air, produce more power, and generate more speed. A cold air intake (which cools air before it enters the engine) can double these effects because cold air is denser than warm air.
The entire purpose of an air intake system is to provide your engine with oxygen, which is essential for burning gasoline to fuel your car. More oxygen means more power from your engine, so improved airflow is an excellent way to increase the performance of your vehicle.
Boosts in Acceleration
Additionally, cold air intakes help boost the engine`s responsiveness to acceleration by offering more air (the colder the air, the more dense) for your combustion, which helps your vehicle reach the desired speed faster.
The 1.7L engine in the 2001-2005 Civic is an interference engine, meaning if the timing belt breaks, the engine might get damaged.
Honda`s high-output i-VTEC (“i” for intelligent) 2.0-liter dual-overhead-cam four-cylinder engine produces 160 hp and 130 pounds-feet of torque; it drives a close-ratio five-speed-manual gearbox.
The latest “improved” manifolds can often generate an additional 20, 30 or even 50 or more horsepower on many of these larger displacement engines compared to what was possible using an older manifold design. Runner length also affects the rpm range where an engine makes the most power.
Cold air intake – Cold air intakes will improve fuel efficiency, only to the extent that they are actually delivering colder air versus your stock intake. Air cleaners and filters – Air cleaners and filters generally don`t produce much in the way of fuel economy.
There is no harm to the engine by having more air enter the system. It may make the engine run easier. Just make sure that the air is filtered.
Are cold air intakes bad in the winter? Ans. No, in fact, cold air intakes work better in cold weather because the intake air is denser and contains more oxygen in the same volume. This provides more power during combustion of the air-fuel mixture resulting in higher horsepower, better fuel economy and lower emissions.
The more oxygen (air) that flows into the engine, the more fuel that can be burned, and the more power the engine can make. To say it another way, assuming you mix the correct amount of fuel with the air, how much power an engine can make is dependent on airflow.
Have you ever wondered why your car may or may not go from 0 to 60 mph in 2 seconds? Well, it has everything to do with the torque and horsepower on your car. These two features essentially determine the speed of your vehicle. The higher the torque and horsepower, the faster you go.
Does a K&N system really increase power? Yes, K&N intakes really do increase horsepower and torque; in fact, it`s guaranteed. One of the fastest ways to add more airflow, horsepower, and throttle response to your vehicle is by installing a cold air intake.
Cold Air Intake
: Bottom Line
Cold air intakes enhance your engine performance by increasing horsepower and responsiveness when accelerating. They can also boost your fuel economy, saving you money on gas.
Upgrading from a stock filter to a cold air intake is one of the best and easiest ways to increase horsepower. They have special filters that increase the surface area that pulls the air into your engine. Not only do they increase the amount of air that`s taken in, but they do so while the air is still cool.
THE CONS. One of the primary disadvantages of installing a cold air intake is that the chances of water entering the engine will be significantly higher. This can ultimately result in a hydrolock, a state wherein the engine stops spinning because its cylinders has been filled with water.
Cold air intake systems are great because cooler air is denser and more oxygen-rich than hot air. To put it simply, your engine will see a power gain with cooler, denser air, also helping the car`s fuel efficiency.
When you introduce a high volume of cold air to the combustion process, the engine is able to burn the fuel more completely, and that results in additional horsepower. So yes, a cold air intake system does work.
