Ive heard good things about the coolingmist. snow makes a good one too. just be really careful not to run too much meth. I would stay away from it if you don have studs. Also, personally I wouldnt recommend it as a performance addition. meth has a tendency to blow headgaskets on 6.0s. If I decide to go that route on my truck ill only run water for the cooling and no meth. Also heard of people melitng pistons from too much meth in a mixture. If you run the blue (-20) washer fluid you should be OK, it is about 20% meth I believe. just never more than 50/50 mixture and I would never really suggest more than 25 % meth for everyday use. Also be sure your tuner knows your running water meth if your running SCT.
