What is the difference between a cold air intake and a ram air intake?

 

cold air intake (CAI) is where the air being taken in is coming from a relitively cool area normally in a mass amount. ram air is just a large filter that intakes a large amount of air in a short tube.

best way i know how to tell you google each and look at pictures that kinda helps get an idea

 

true ram air is forced into the intake...

 

appreciate it thank you for answering my rookie questions
