Agreed, I removed mine as well because I owned a Cobalt SS/TC and saw that they don't come with an engine cover so I took mine and how about that, engine runs cooler. Another small easy mod that further drops temps is opening up the fake vents on the sky. From that alone I saw a drop of 5*. Now I typically run from 188-203 at most.
