Fit perfectly! Instructions were clear,but I opted to have it installed professionally anyways as the intake manifold needs to be removed. Glad to have ice cold ac again!

I don't have a machine to make these, but if I did, I am sure I could sell them for a lot less than this. However, since I purchased these for work, and in the end the customer paid for it. I am okay with it. Still, this is a LOT of money for an aluminum block and a couple bolts.

Looked great, but we ended up selling the car before we could use them.

Worth the money. After getting a $1900 quote to replace the rear evaporator in my 2010 ford flex I decided to try these to block off the rear and only use the front AC/ Worked great! Easy install, well made and only cost me 150 bucks to get the system leak tested and charged. Nice to have air conditioning again!
