This performance booster for my car’s AC system did absolutely nothing. I followed all the instructions, adding the recommended amount to my system, but saw no improvement in its cooling efficiency. The air conditioning still struggled to cool the cabin, and it didn’t seem to be any more effective than before. Despite claiming to boost the performance of the R1234YF refrigerant, it didn’t make any noticeable difference in the airflow or temperature. I even waited several days to see if it took time to kick in, but nothing changed. It felt like I just wasted my money on a product that didn’t do anything it was supposed to. I was hoping it would improve my AC’s performance, especially during hot weather, but it simply didn’t work. The canister wasn’t even particularly easy to use, as it kept getting stuck when I tried to attach the nozzle to my system. I wouldn’t recommend this product to anyone, and I will be looking for other options to fix my AC problems.

First can I’m sure I lost quite a bit but once I got the hang of it it was quite easy. This is the best alternative to taking it to a shop for them to steal your money. It worked well on my 2018 Lincoln Navigator Reserve. I thought it was well worth the money. It fit perfect.
