Thats a pretty good deal. That is the kit number that most are running. It's the dry kit specified for pretty much any application. IIRC those kits usually go for more than 600 plus shipping. Also, that kit is super easy to install (1 ground wire, 1 power wire and run wires for your switch, you have to splice into a TPS wire, reroute a couple vacuum lines, and of course mount your bottle, run the lines, and install the nozzles). Very cheap fun... just make sure you get some colder plugs and run nothing but premium when you plan on spraying.
