Derale Tube-Fin Engine Oil Cooler Kit w/ Sandwich Adapter (Multiple Threads) - Class III
Installed this product on my 2013 Ram 5.7 Hemi. Install was simple and straight forward. I hoped there would be improvements in the operating temperature of my engine oil, which there was. Now towing my trailer is no worry about engine oil temp. This cooler works exactly as advertised, and the temp never go above 220. An unexpected result was better gas mileage by almost 2 additional miles per gallon. Also the truck runs much quieter than before and smoother. This noticed by my wife who rides with me always. So I would defiantly call this a win win install and purchase.
It doesn't fit my car even though the website said it would. I had already installed the radiator component before i found the filter adapter didn't fit so i couldn't return the product.
