In our last post, we tackled the cold air intake and how it works. Now, we’re going to discuss another variant of it - the ram air intake.

A ram air intake is usually found on high-performance vehicles and it differs from the function of a cold air intake greatly. The cold air intake cools down incoming air into the vehicle, packing more air molecules to deliver more horsepower.

On the other hand, a ram air intake employs the use of a dynamic air pressure to greatly increase the massflow of air that enters the engine. The dynamic air pressure is created by a moving vehicle in its effort to increase static air pressure that enters the intake manifold of an engine.

This aftermarket performance part also works by acting as an intake air velocity reducer. It does this feat by boosting the cross sectional area of the intake ducting. The increased air pressure is then mixed with the fuel. Once this happens, there will be an increased amount of air to be burnt with the fuel and a boost in performance will be achieved.

The ram air intake has been used since the sixties and it seems that more people are using it to increase the performance of their cars. The ram air intake is a significant add-on for any drag racer who’s planning on having the best parts installed on their car.
