I have Love Jugs on my 2010 103 Limited, have had em on for about 3 years now.
They do cool your heads 100 degrees. They run underwater. (Rains like a MF here in Florida) They plug right into your stock aux plug under your seat, makes for a easy installation, they work off your aux switch. You don’t hear them when your motors running. Have had No problems with them. – jamesroadking – H-D Forum
