Being that I sold my DD and am driving the S4 daily, the N2O is just not something I am going to want in my everyday car. This kit is in perfect working condition, includes tons of jets (50,55,65,75,100,125…I believe). It also includes a NOS bottle heater, pressure gauge, WOT switch and circuit (although not needed on normal TPS cars). One of the brackets that holds the bottle in is broken but can be obtained fairly cheap or possibly repaired.
