Free Mods are: the egr that sits in your intake top front bronze looking, one bolt un screw pull up cut flush.
2ND demask your mass air flow sensor four allen wrech screws.
3rd Throttle body by pass, didn't do myself I live in Colorado...
First bolt on should be headers to free up your engine for other mods, best hp for the money. intake money to hp ratio is bad
