I was a skeptic of all oil coolers but was I ever WRONG! The Ultracool and oil filter kit brought my oil temp down on average 45/50 degrees. I live in SoCal and have a 5 mile dirt/sandy road to get to my ranch. My 2015 Roadking on a hot day the oil temp would reach 290 / 298 way to hot. Now on the hottest day this year my oil temp was 248 and most times never tops 228.. I purchased the chrome grill bottom mount which fit perfectly with my 21 inch rim and looks GREAT and it works!! Great Purchase, Great Product. My only complaint is that I didn’t buy it sooner, as I said I was a skeptic. I love the kit and led light that lets you know fan is on. I custom mounted mine in the Roadking dash and it looks awesome. Thank You Ultracool!!!
