Anybody know the difference in the 03 / 04 Civic intake location, or the difference between the manual or auto?

A friend has a 2004 auto ex coupe and wants an intake, but I have only found the AEM CAI for manuals and the V2 for auto/manual.

I would like to direct him correctly on buying a less costly CAI but I dont want to risk a cheap one that says it will work, not working.

Can anybody help?

Thanks in advance,

Matt
