I live in the sunny south and it has been one hot summer. Purchased the Ultracool for my 2011 Roadking Classic. Oil temp was running really hot in traffic and on very long rides. Since I put the Ultracool on the temp has yet to go above 220°. BTW I love the blue LED that let’s you know when the fans are running. Easy to install yourself and great directions. I would also recommend the FLO reusable filter.
