I went onto car-part.com looking for a intercooler for 2002 7.3 diesel, and it asked me if the truck had a catalytic convertor or not. I was at a salvage yard and they had one from a non cat truck, and also one from a cat truck and I could not see any differences. However, when I called a cooling supplier and asked for a new replacement, they didn't ask me and said they omly showed one listing for that application. Does anybody know what the differences are if any?

 

No differance, What the heck would a cat have to do with a IC???

 

x2, not sure what that is all about.

 

That's what I thought too, but car-part .com shows them to be different for whatever reason
