The first-generation 3.5L EcoBoost runs high cylinder pressure and direct injection, which is hard on rings, bearings and timing components once mileage climbs. Replacing the long block resolves all of it at once instead of chasing a misfire through the short block. Covers 2010-2011 Flex, Taurus SHO, MKS and MKT.
