I own a HD 2009 Electra Glide Standard that I’ve done some custom work to the engine as well as the entire bike. Searched for the best oil cooler I could find after some engine upgrades and did I ever find what I was looking for. Buy this cooler now! My club makes big runs from city to city and down the highway as well and what a tremendous difference this cooler makes. I whole-heartedly stand by this oil cooler when I’m in a traffic jam. Thank you UltraCool and staff for a great product. CJ H-Town
