Here are before and after pictures of my ’07 Streetglide. Ordered them on a Monday, received on Saturday. Installed, went for a putt in the desert heat of Bullhead City, AZ. Temperatures have been between 140 – 120 all week. Used my temperature gun and was amazed. Rode 30 miles with the fans off, temp was 360 degrees oil temp 236 degrees, shut off engine. Turned fans on and let bike idle temp went down to 247degrees oil at 216 degrees. Will do more testing as the summer progresses. So far, I love my jugs. Thanks. Frank C. Bullhead City, AZ
