You generally want an IC core that is "thinner" with more surface area on a DD driven car, esp if you ever plan on using your AC. Also, you want good endtanks not only for the weld quality but also for flow. Whats the point of having cooler air if you have a huge pressure drop and/or a shitty design that doesn't flow? Some people can go and just buy any old core and rig up piping and yes, it'll work. But how well? I'll bet some of the FMIC's out there on the market, that even though are bigger, don't offer much of an improvement over the stock SMIC with upgraded piping. I'll also bet that most people have summertime drivability issues that they just write off as "normal"...
