I did a through test with the Big Sky Fans a couple years ago and was extremely disappointed. First off, for the money charged, $105 bucks, I was in total shock when I recieved the parts. You get two fans, connector and wire. After I purchased I found the exact fan on Google for $14 bucks, so if you are intent, search fans on Google. Secondly, before and after I installed the fans I recorded several riding episodes with and without the fans running, all test were recorded during a 98 degree summer weekend. To make a long story short, I recordered hotter temps with fans installed regardless if fans were running or not. I also noted a drive through down town Napa, during a busy weekend with fans runnning, my engine temps quickly reached 305 degrees with apsoutely no cooling effect from the fans. As usual, I pulled off at a water hole and enjoyed my fav beverage. The BigSky fans are a total waste of money, and I wouldn't put much more trust in the Jag Fan arrangement recently on the market. TRUST ME.... DO NOT WASTE YOUR MONEY ON THESE SNAKE OIL REMIDIES,, THEY SIMPLY DON'T WORK. If they did the MoCo would have them on every model.. Now for the Big Sky dealer guy,, if you feel like buying him an expensive drink,, buy his fans,, he'll be smiling at the bar waiten for another free drink.

bye the way
