How does a cold air intake work....i know that air when cold its compressed but how does a tube and a filter help???

please explain or link something cuz i wanna know

CAIs are good for two reasons.

1. They pull air from outside of the engine bay where it is cooler and more oxygen rich (which means more hp).

2. When designed correctly, they will create a high pressure area in the intake tract and actually force the air into the engine. That is often called "Ram Air" and helps the engine turn more RPMs and make more power, in general, as without that effect, the engine relies soley on its ability to suck the air into the engine through the intake system with the vacuum created by the downward movement of the pistons.

Cold air is "denser" meaning it is packed full of more molecules that can carry more fuel and in turn can be packed into the cylinder. The filter allows the engine on the same intake stroke to "inhale" more air to pack into that cylinder. Remember an engine is an air pump. The more air you can get in it per stroke and burn efficiently the more power you can make.
