I ordered the cab cooler kit and it really works as advertised. It gets a little warm down here in south Texas and I had already tried wrapping the coolant pipes, covering the center console with reflective heat tape and a couple of other things, but nothing really worked. Put in the Wolfsnout kit and it actually made a huge difference in getting rid of the in cab heat.
Really nice people to deal with too, they hand package all the kits so when I received mine I realized they had left a piece out so when I called him up he apologized profusely and got the piece on the way then took the time to explained in detail how everything went together since they had recently changed a couple of things.
I actually just ordered 2 of the dust masks a few minutes ago because of all the good reviews and my own experience.
