What's the Difference Between Cold Air Intake and Air Intake

The reason is simple: cold air is denser than heated air. Since we already know more fuel mixed with more air equals more power by using cooler, denser air, a cold air intake is able to add more fuel per-unit-volume of air. This is especially important when the car is moving slowly or starting from a stop.

Which is better cold air intake or warm air intake?

How much HP does a cold air intake add?

It makes such a big difference, in fact, that the simple process of redirecting the filter to draw cooler air is good for a horsepower gain of about 5 to 20 ponies in most cars. It might even improve your fuel efficiency, and it’ll probably make your engine sound better, too.
