My truck popped out of park and hit a tree busting my bumper, hood, AC condensor and it bent my intercooler. This may sound dumb but, Should I replace the intercooler. It is bent a little but I couldnt tell any difference in power or boost after driving it. The comb on the intercooler is in fairly good shape. Any help is appreciated.

 

As long as it isn't leaking, you could run it. It may not be as efficient, but will work.

 

what is the easiest way to check for leaks?

 

Pressurizing the entire intake system, and listening and looking for leaks. Have a look at this thread:

Windex or soapy water will help identify leaks.
