KDoerr said:Air Dog is No good I live up in Canada and I never had the filters freeze up on me. Buddy of mine has Air dog and mounted it on the skid plate and now in the winter he has to crawl under the truck to remove the ice and the snow from the filters. So IS IT BETTER? FASS you mount it and you are Done and with over a millon Km and no work to the FASS I'm not complaining.
I would think it would be warmer by the transfer case. If he is still having trouble he can get a mount to put it in the normal location (outside frame).
