Teardown Reveals Refreshed Apple MacBook Air Laptops Still a Bear to Repair
According to iFixIt, a 180-degree rotation of the mid-2013 MacBook Air gives a glimpse of the only noticeable change to the exterior shell, which comes in the form of dual microphones along the left side. You still need a special Pentalobe screwdriver to get inside the thing, though once you remove them, it's pretty easy to crack open.

Once you pop open the chassis, some changes versus the 2012 model are immediately apparent, including a smaller SSD module, updated AirPort card, no separate platform controller hub, a new heatsink clamp, and opposite-facing speaker cable connectors. There's also an upgraded battery, 7.6V and 7150 mAh versus 7.3V and 6700 mAh.
When all was said and done, iFixIt gave the mid-2013 MacBook Air a rather low 4/10 score on its repairability scale. The main reason is because of all the proprietary parts, including the Pentalobe screws, RAM, and SSD. And unfortunately, the RAM is soldered to the logic board, a poor decision considering RAM can go bad and is pretty cheap to replace.
