I’ve put approx. 30K on my bike since I installed the UltraCool oil Cooler, I ride a lot of miles all over the country each year, I’ve noticed a huge difference in not only my oil temp, but the heat coming up the my legs, (Ya’ll know exactly what I’m talking about) it’s not nearly as bad! I would recommend this to anybody who cares about their engine lasting, I have a 2008 Streetglide which I’ve put all 64K miles on, and I plan on keeping it for a long time!! UltraCool has nailed it, I looked at a lot of Oil Coolers before I decided on this one. It’s not hard to install, it’s automatic, Goes on when it’s supposed to, and shuts off when it’s supposed to, worry free!! The guys at the shop ride just like we do and they really care deeply about this product. That’s what I look for when I put anything new on my Bike… Great Job Guys!!!
