i bought a used f250 07 6.0. First thing i did was get egr delete and add an oil cooler. So far I've had to replace one injector and one glow plug. Other than that its been good. Biggest thing make sure you do regular oil changes(5000 miles) on these 6.0's!! My mechanic worked at the ford place for 17 years. He drives an Excursion with a 6.0 and his personally opinion is the 6.0's the best out there.
