| One of the
easiest ways to add horsepower to any car is to draw cold air into the
engine intake and to keep various engine parts cool such as the alternator
or other independently powered devices that may generate heat. Using
a cold air intake (CAI) to route air into the engine from outside the
engine bay is an effective way to increase horse power.
Cooler air is more dense and oxygen rich. The more oxygen the
higher the compression in the cylinder and the greater the
horsepower. At the high revolutions the stock engine intake system
can also restrict airflow. The combination of hot thin air and
restricted flow can cause an engine to run "lean" robbing the engine of
horsepower. |
