warranty
i bought a 2006 f350 sd crew cab auto 4x4 6.0 in 2007 they said 3 year 36000 bumper to bumper 5 years 100000 miles on all drive train diff trans transfer & engine but i had to use ford filters and oil
easy way to make daytime lites turn lites on auto and cover sensor on dash with black cap from soda or anything with black cap that fits over little round sensor on dash
i made one and used it for awhile got 1.to 1.5 more mpg coudnt keep it from leaking still thinking also if i got enough gas also got to much heat still thinking about placement and cooling system and better sealing of unit
