Easy install (though lengthy), you need coolant, spark plugs, and fuel disconnect tool (unless you do it like I did and left the fuel rails connected and put them on in the engine compartment instead of on the ground). Also get some wire cutters and crimpers along w/ solder and a soldering iron for the most professional look when done (and reliable). Get some heat shrink tube to, they give you some but I bought some more anyways, I am anal when it comes to my car. You may also want to think about getting a little longer radiator hose (on my 01GT) it was a little short, I made it work but I don't like how tight the fit is. Good luck man
