I say you should get a cai for the CRX I think it would fit better, actully you should call the company you are going to purchase it from and ask them what they think I mean they made the damn thing right? and I bet alot of people ask the same question so they should have a answer for you. or you could buy a short ram intake for a CRX that would definately fit, then make a custom Ice box for it. Good luck on what ever you decide
