I have a 6.7 F350 Single rear wheel short bed and I absolutely love it. I sold my 04.5 Dodge that I loved and this new Ford is way above my Dodge. I get 19.5 mpg and it tows our 12K horse trailer great. So much power and it rides great.
Sullivan, who can do this work, this might be a good thing for me to do on my 6.4! thanks
EGR? DEF? Is that all the particulate air filter crap that comes on?
