Not sure about comparing the kits, I almost went with another company but decided on Classic Auto Air, their kit was new to market when I got it like a year plus ago. I like the aftermarket kit, connections to firewall can be clean, not too much box under dash. There was something about the evap box inside that was better with CAA, it could be opened & repaired if needed, case not glued shut or something, plus CAA used large coils or something. I do recommend CAA having been thru the whole kit, I still need to get AC dialed in by pro.
