So guys with electric fans,
How are they?
Was it worth the price and install?
How is the power and mpg gains?

Actually I've been looking into this, I think I'll go the junkyard route. Look for an old Taurus or Lincoln Mark VIII electric fan. Most sell for about $30, then get a good fan controller for about $50, must cheaper than buying one and the Mark VIII fan pulls about 5000 cfm. They also sell em on Ebay but they gouge you on shipping but still cheaper than buying a new one.
