I have a Dyna and I just installed the 3.0 Ultra Cool dual fan assist oil cooler. I live in Arizona and this is amazing. Keeps the temperature around 210° F  The directions are easy to follow. The kit comes with everything you need. It’s extremely well-made easy to install,. I was taking my time and still only took about an hour and a half from start to finish. The directions are easy to follow and made the installation and wiring super simple. It’s the best thing I ever bought for my Harley and now I can ride a little bit longer in our crazy heat
