Don't waste your time or money on this product, buy O.E.M. from the start. I replaced my DEF heater with this Dorman replacement. It lasted less than 100 miles! This is not the first time that I went with a Dorman product and got burned...NEVER again, I finally learned my lesson. After years of working as an auto tech and using what use to be a good replacement product, it saddens me to see their decline.
