It did seem well made, I was happy with it. As far as performance, I didn't necessarily notice a change. I did put puller fans on the car, so the AC does start to get warm when sitting at a light too long but once air starts going through the condenser the AC works like it should.
If you didn't see the thread to improve AC performance, I highly recommend it. I removed the plate in the footwell and it was a huge difference! There are many more mods in it but that was the only one I wanted to do because it had the greatest impact
