Adds 100HP easy!
Well not really..Although it is an easy way to release you from the herd of us 5.0 owners..
Fitment is okay, quality is damn sure not worth 450 new.
There are 2 minor paint chips very easy touch up job, and all you will need to do is remove the 3M tape on the brackets and put more on and you're good to go.
$100 OBO..
