A cold air intake or CAI is typically an aftermarket assembly of parts used to bring fairly cool air into the car’s internal-combustion engine. Cold air intakes move the air filter outside of the engine compartment so that cooler air can be drawn into the engine for combustion.

Cooler air brings more oxygen into the combustion chamber, and that suggests more power. The filters are generally relocated to the upper wheel well location, or near a fender where there is more access to totally free flowing, cooler air, and less heated air from the engine.

The advantages of a cold air intake are significant. Consider it by doing this: your car’s factory air intake system has a cold that congests the head and limits its breathing. It can not run well under this scenario. So, a cold air intake works as a great “medicine” for the engine to operate at full performance.

What’s more, not just does a cold air intake minimize the air temperature, but it likewise increases airflow.

Cold air intakes eliminate the requirement for a box surrounding the air filter, and rather utilize large size intake tubes that are smoother, have less bends, and are frequently wider than the initial factory variations. Getting rid of the air box and using smoother tubes provides the engine continuous airflow.

How Cold Air Intakes Work
