I have 2007 FLHTC Harley which was converted to a trike champion. Been running Amsoil in it for years before conversion kit ran cooler but not cool enough. But one of the first Ultram oil cooler. About 10° cooler ran. Couple months ago I called and asked what was the new coolers difference was. So I decided in getting the new Ultram cooler seen the big difference of 15° till 18° cooler in the unit looks like it’s a lot a lot heavier very happy with. I live in Arizona so it is hot here running on the highway. I run oil temperature gauge on the highway runs around 220 and 210 in town is up to about 235 to 240 Max so I’m real happy
