cold air intake

[chevyman2004]

this maybe a stupid question but what is a cold air intake and what does it do?

[Chevyman224]

It cools off the air going into your engine and lets more air to go into your engine allowing it to breathe and create more horsepower and some extra mpgs, also better throttle response

replaces the stock restricted air box, usually with an open air element and better flowing pipes to the intake

to make it a true ram air you can buy an hose that attaches to the hole on the filter and run it down inside you fender to the front of the vehicle this way it sucks the cold air from outside, my opinion on just installing the cold air intake with out the second hose is that it's just sucking hot air from your engine and then it doesnt do anyhting really besides making your vehicle sound a little better.
