Love my stage II snow performance kit. Have 2 nozzles(625ml and 175ml). I only use it when i see a steep grade coming up or if i get on it hard. The stage III kit is the ultimate water kit from snow with more adjustability than the stage II. Like extentedpower said...i've seen 200* temp drop in my egts using mine. When it comes on at full tilt, i can really feel the power difference and hear it in the exhaust tone.
