Frequently Asked Questions About Cold Air Intake System

a) Does Modifying My Car Go Against Factory Warranty Terms?

Unless specified by the car manufacturer, warranties should stay as they are. Modifications are made on cars all the time and are part of owning a car. However, be careful to confirm the return policy and warranty terms before changing the cold air intake system.

b) Is Cold Air Better Than Warm Air for the Engine?

Combustion happens in the engine. Therefore, the chamber tends to heat up and needs cooling every time. Cold air not only supplies oxygen into the system but provides oxygen for the fuel to burn efficiently.

c) Is a Larger Air System Better Than a Thinner System?

A larger air system allows more air into the tube and further into the combustion chamber. The faster the air passes through the air filter and into the tube and chamber, the more efficiently fuel will be consumed by the engine. Many cold air intakes have a large system to reduce any resistance to air that needs to get in at high speed.

d) Is the Hissing Sound During Acceleration Normal?

Yes. Most of the time, the hissing is due to the airflow through the air filter. However, the sound may be a sign that there is a leak. Check for a leak whether the engine light is on or not. A leak can lead to reduced engine performance and poor fuel economy.

e) What is the Difference Between Dry Air Filter and Oiled Air Filter?

A dry air filter is made of paper or foams that filter when air flows through them. On the other hand, oiled filters are made of cotton material coated with a thin layer of oil to trap any contaminants that might pass through into the combustion chamber. Dry filters function efficiently and are hard to beat at cleaning the air. However, the filters do not let in as much air as their oiled counterparts do, reducing the engine's efficiency by a large margin. The stock airbox traps a lot of dust with time and significantly reduces the air that gets into the engine. Less oxygen leads to incomplete combustion, which is a waste of fuel in the longest run. Dry filters are not reusable most of the time, as washing them will ruin the paper used to make the filter. The best method to clean the filter is by using compressed air to remove the excess dirt.

Oiled filters, on the other hand, are more open and cool air as it comes in. The filter can then channel air into a tube that increases the speed and accelerates the combustion process for efficient fuel consumption. The filters are reusable and washable and can last longer than the dry filters. However, the oiled filters need more maintenance and regular checking. Over-oiling the filter can destroy the Mass Airflow Sensor. The oiled filters still come on top when you have to choose between the two.
