Performance Aftermarket Honda Acura Intake Systems

The air intake system"s job is to take outside air, clean it and deliverer it to the engine so it can be mixed with fuel and burned. Sound like easy task but there is power that can be unleashed. The engine is a giant air pump, the easier the engine sucks air less power is being waste to get the air inside.
The first solution to this is a drop in air filter. K&N makes OEM replacement high flow air filters for nearly every car. The K&N filter uses a free breathing filter that can flow up to 100% more air then the stock air filter. The K&N filter is also very durable and can be washed and reused many times over and over again and saving you a lot of money. Usually the horse power gain from a drop in filter is from 0-2 hp. The limitation of a drop in filter is that the size of the filter is the size of the filter originally designed by the manufacturer. If the car was designed with a tiny air filter your drop in filter is going to be tiny too.
The second solution is a cone style open air filter. These filters are racing type cone shaped air filters with a large area for filtering. The bigger the surface area of the filter the less restriction for the incoming air flow the filter will have. Cone filters usually have an adapter that bolts on to the cars intake pipe, replacing the stock air filter and air box. Cone filters typically give you between 2-3 hp gains.
The third and best solution is an air intake system. The air intake system could be a short ram air intake or a cold air intake system. Most of the air intake systems, no matter short ram or cold air intake, use mandrel bent pipe to replace the restrictive stock rubber pipe. Most of these pipes range from 2.25" to 3" in diameter and from 12-30 inches in length. Some of these systems can be plumed to the front of the car to take high pressure air coming from the front of the car. Air intake systems can be plumbed to the outside of the engine compartment to take advantage of the outside cold air. The colder the air the more oxygen it contains and it is denser these is where the extra power comes from. These systems can produce from 4-6 more horse power. Air intake system can increase the gas mileage too by reducing pumping losses. There is a downside of a cold air intake systems and that is that they can pick water from the road in a rain storm which can damage your engine. They can pick up water because the air filter is mounted all the way in the front bottom of the engine compartment. Many cold air intakes such as AEM have a removable section so the air filter can be mounted quickly higher in case of rain. Some of them has a special bypass valve that is going to redirect the airflow to a higher intake if the intake sucks up water.
Air intake systems and cone type filters are much louder then the stock air intake system, so if you are sensitive to noise that it is a thing to consider when building a performance Honda, Acura.
Performance air intake can be installed on Prelude, Civic, Integra, Rsx or any other model Honda Acura car.
