“Naked” Black ***We are revamping this kit with less cutting of the lower fairing. Available December 18 2023
Out of stock
Requires permanent modification of left lower fairing. View the installation guide here:
This kit designed for the "Liquid Cooled" Twin Cam engines that only water cool the exhaust ports on the engine. The stock cooling system simply is not enough to keep these Twin Cams from overheating in traffic and city riding. Adding a FLO Oil Filter and our 3.0 UltraCool Oil Cooler gives these engines the performance of a FULLY liquid cooled! Don't believe that bold statement? Just read the reviews by clicking on "Reviews" at the top of the page. **Note: This kit can also be used on 1998-2016 non liquid cooled Touring Model engines that have HD lower fairings although our Below Regulator Mounted version is generally a preferred option for those models.
UltraCool is back and better than ever with its new Side Mount Oil Cooler! Some cool new features including:
- Fits FLH Frames 1998-2016
- Side Mount on Down Tube
- This "naked" version is designed to occupy the space of the left lower fairing air door.
- 3.0 Oil Adapter and Thermal Switch with waterproof connectors automatically turns on the powerful dual fans when your oil reaches 210 degrees and they stay on until the oil is cooled to 185 degrees. UltraCool's goal is to keep your oil at the optimal temperature of between 200 and 230 degrees.
