Own a 2013 HLTK Ultra Limited, bike always ran hot in summer traffic. 2015 Sturgis traffic was murder on the oil temp. Researched all I could find, settled on UltraCool because of the 220cfm’s of air moving across the heat-exchanger. No air, no cooling. Was a bit of job to install, tight fit with side pods in the way + I’m not as young as I once thought, lift definitely helps. All parts fit as advertised, videos were major help when running the oil lines. Thus far ***** rating.
